This section covers topics of genetics such as variation, pedigrees, Mendelian genetics and mutations.
1)Penetration, 2) Biosynthesis>(Early phase - Middle phase -Late phase ) 3)Gene regulation biochemistry, 4)Maturation andlysis, 5) Productive cycle.
Generally, the source of energy for cell functions is ATP or  Adenosine triphosphate.
A room and a cell are alike in that they are isolated parts of acollection. The rooms have walls which separate them from the otherrooms of the house, and the cells have cell membranes (and cellwalls for plant cells) which separate them from the other cells inthe tissue. However, you can take the...
RH factor in blood types stands for "Rhesus Factor". Blood testswere performed on Rhesus monkeys and the Rh+ and Rh- factors wereisolated. An antigen found in the red blood cells of most people:those who have Rh factor are said to be Rh positive (Rh+), whilethose who do not are Rh negative (Rh-)....
bacteria is not a plant or an animal because it is single-celled. plants and animals have many cells.
the membrane of the tympanum or ear-drum.
Storage location of DNA, and are used to pass on genetic traits.
In 1665 the first biological cells were documented by Robert Hooke.  He looked at thin slices of cork under a microscope.
The phenomenon of multidrug resistance is correlated with the presence of a membrane protein, P-glycoprotein, which pumps a wide variety of drugs out of cells thus reducing their toxicity. This is similar to "flippase" but the mode of action is unknown. It requires energy as do all enzymes and is...
That depends on the life cycle of the organism. Geneticists oftenuse fruit flies for that reason as they reproduce quickly.
I wouldn't say that. The main purpose of respiration, that in  biochemistry is known as "oxidative phosphorylation" is to produce  ATP molecules. A complete chain of an oxidative phosphorylation  pathway goes from a molecule of glucose that is degraded into  smaller molecules, passing through...
Seeds are enclosed in fruits. Leaves are usually broad and flat.Flowers are presentbut cones are absent.Fertilization Is double.Angiosperms are divided into two major groups ....1. Monocotyledons2. DicotyledonsIn angiosperms, the reproductive structures are located in the flower, which consists of...
Cytoplasm comprises most of an animal cell, so it's about the sizeof the cell. In a plant cell you have a large vacuole so it'ssomewhat smaller.
Digestive and circulatory systems.
Around 80 to 90 percent. Acurracy: 85.55%
To control what goes In and out the cell
DNA stays in the nucleus it safe there. it won't get lost in the cell
DNA is not copied in mitosis but in s phase of inter phase .
To be more accurate the nucleus doesn't split in mitosis because  after DNA replicates in interphase and prophase starts nuclear  membrane is removed and there is no longer a nucleus just free  chromosomes. These separate in anaphase and then in telophase where  two daughter cells are going to...
If you have both, you have a lot of influence on a LOT of people.  And, depending on how good your heart is, you'll make good choices.  But, unfortunately, generally speaking, not very many people remain  good at heart with a lot of power and authority in their lives.
G1 phase, G2 phase of the cell cycle
A molecule of pyruvic acid (C3H4O3) contains 3 carbon atoms, so one  molecule of pyruvic acid will form 3 molecules of carbon dioxide  when it is completely oxidized to CO2 and water.
Inheritance, segregation, and independent assortment. He used pea  plants in his experiment, this was generally genes and punnet  squares and how they worked.
not a very bad (effective) symptom
DNA has four different bases. The bases of DNA are adenine,guanine, cytosine, and thymine. Thymine is the smaller pyrimidinesand Guanine are the larger purines.
In which sentence is the italicized word used correctly   A. Its the bottom of the ninth inning and the bases are loaded. B.  Can you grab my phone ? Its on the Table. C. The cougar stalked  it's prey through the jungle. D. I closed the door because it's  freezing in here!
this is the process of photosynthesis...it all starts with the DNA,  the mRNA copies the genetic information from the DNA and makes a  strand of mRNA, this is then transported to the nucleus where the  tRNA combines with the mRNA to make codons (3 bases=1 codon) these  codons then go into a...
First, the plant undergoes photosynthesis, as normal. Once the  glucose is produced, it is turned into starch through a process  called polymerization. This happens in the organelle known as the  amyloplast. Once the amyloplast has turned the glucose into starch,  it moves the starch to the...

Hormones are usually made out of proteins and lipids. Ribosomes  make proteins. Skin is also protein. But most likely, more hormones  are made in a hormone-producing cell (called an endocrine cell) in  a faster turnover than a skin cell. Thus, there would need to be  more ribosomes in the...
I wouldn't call them side chains, a term which refers to part of a  branching carbon skeleton. The two functional groups involved in  bonding are the carboxylic acid group, -COOH and the amino group,   -NH2.
The more substrate the faster the rate of reaction up to a point where it levels out. Basically the enzymes and substrates bounce around until they meet the substrate that the enzyme can catalyse so obviously with more substrate there's more chance of he enzyme bumping into the right substrate
  the Gene is a term or tree
The performance-intensity function plots a listener's performance on audiologically assessed speech tests at various intensity levels "(loudness") to determine the maximum speech discrimination or word recognition scores, aka PB max.
     Genotype (DNA)     Blood Type     (+  , -) or (+ , +)  Rh  +    
DNA's code is written in only four 'letters', called  A,  C,  T and  G. The meaning of this code lies in the sequence of the letters  A, T, C and G in the same way that the meaning of a word lies in  the sequence of alphabet letters. Your  cells read the  DNA sequence to make chemicals...
Absolutely not. Blood tests exist so that couples will not be at risk for HIV, AIDS or other diseases.
two capital or two lowercase letters in the GENOTYPE (ex: TT or tt)  it's also called HOMOZYGOUS.
Not get your meaning clearly. Maybe you can find answers by  visiting Creative Biomart's website about gene expression.
Nucleic acids are the building blocks of DNA and RNA.   The five nucleic acids are:    3 pyrimidine bases: Cytosine and Thymine (or Uracil in RNA)   next to   2 purine bases: Adenine and Guanine.   None of them contains an amino group which is essential in protein  formation of...
Both Prokaryotes and Eukaryotes have proofreading mechanisms built  in that read newly synthesized DNA strands and check for mutations.  Then by utilizing exonucleases and ligases they can cut and remove  the mutated base pair and religate the DNA (join the ends back  together again). One way...
Sperm cell.
A cell with no cell wall, just a cell membrane. Such as an animal cell.
Yes, DNA and RNA have different sugar . DNA contains deoxyribose  sugar whereas RNA consists of ribose sugar, which are completely  different from each other.
About 98% of human DNA is termed non genomic! Much research is  required to elicidate what the all the other information codes for!  The question is not scientific as it appears to pesonalise the  situation and is not specific enough meaning it is open to  misinterpretation as a result! Not a...
If you mean 5.18M, then no.
 Histology is the study of tissues and organs through the  examination of the microscopical architecture of tissues and the  relationship between the different types of cells and tissue types  found within tissues and organs.
Carbohydrates, Lipids, Proteins, and Nucleic Acids.
I'm unsure of what you mean by 'goal' but I'm pretty sure you mean  'purpose' in that case:   DNA is the blueprint of life. It dictates eye colour, bone  structure, blood type, basically everything about you.
By Sexually Transmittive Disease or by germs. Brought to you my  your mother.
The best course of action is to confront him about it. Say youfound that he was doing this and you don't like it. If you don'tsay anything, it will keep happening.
Multiple alleles is when there are more than 2 alleles in a single  trait. In blood type, instead of either one dominant and one  recessive type alleles, there is one recessive allele (type O) but  two dominant alleles(type A and B). Polygenic inheritance is when  more than one gene controls a...
This depends on the stage of life. Before birth, the spleen produces red blood cells in the fetus and a shortly before we are born, the red blood cells are produced in our bone marrow.
The process of (aerobic) cellular respiration combines a  carbohydrate with oxygen to release energy. This oxidation reaction  is the "reverse" of photosynthesis.
In the m-phase the cytoplasm is split by a cleavage furrow.
Spherical, heterogeneous aggregates of proliferating, quiescent,  and necrotic cells in culture that retain three-dimensional  architecture and tissue-specific functions. The ability to form  spheroids is a characteristic trait of CULTURED TUMOR CELLS derived  from solid TUMORS. Cells from...
There is a greater risk of infections.
Down syndrome is caused by the presence of an extra 21st  chromosome. Instead of the typical 2 copies, a person with DS will  have 3 copies (known as a trisomy).   Down syndrome is not a mutation, but is usually an inherited  condition due to the extra genetic material in one of the parents' ...
Yes, imagine a grain of rice with a tail.
One of Virchow's major lines of work showed that the poor general  health of the poorer classes was related to their social  deprivation.
The mass of a cell which has not been dehydrated.
Apparently yes they are.You can look at it in the chromosomal level.Genes from both male and female are passed down to the child.A good example is the sex chromosome.Male gives X or Y and the female gives only X.
  == Answer ==   Endotoxins are potentially toxic, natural compounds found inside pathogens such as bacteria.
Yes, it is found in pairs Adenine with Thymine and Guanine with Cytosine...they are directly across from each other (horizontally) on the DNA line ( also known as a double helix) there can be many of these on one double helix
It is a type of genetic disorder in which females are affected.  This happens when they dont have an X chromosome as in the sex  chromosome so the resultant will be XO.
The function of the cell wall is to help protect and support the  cell.
There are various variables. Sometimes when a woman is in their  40's two eggs can be released at the same time. Some woman has the  condition known as hyper-ovulation. Women with this condition tend  to produce more than one egg in a cycle. This can be genetic on the  maternal side. The result...
Not too much. Actually the genes are quite similar between human  and other species. For example, there are 99.9% similarity between  human being and ape. For human and pig this number should be around  99%.
