Why can differences in mitochondrial DNA be used as derived characters?
Derived characters are used to produce Information. Sperm Cells are too small to contain mitochondria so that the {in a fascinating way} the Dna that is only found in Mitochondria {in the Ovum} is not passed along to the male offspring. That's Why Sprite.
So that was the Intro.
If you can believe it the mitochondrial analysis shows that Humanity at one point {in Time} was at about one thousand Peoples.
Do bacteria have enzymes for performing metabolic activities?
Yes, bacteria have enzymes that help them perform various metabolic activities such as breaking down nutrients, synthesizing molecules, and releasing energy. Enzymes are essential for the functioning and survival of bacteria.
What is the dispersed phase in milk?
The dispersed phase in milk refers to the tiny droplets of fat suspended in the water-based liquid portion of milk. These fat droplets give milk its white color and contribute to its texture and flavor.
What causes Sanfilippo syndrome Type A?
caused by a deficiency of the enzyme heparan sulfate sulfamidase, due to mutations in the SGSH gene on chromosome 17. Type IIIA is felt to be the most severe of the four types, in which symptoms appear and death occurs at an earlier age
Does pH effect enzyme activity?
Yes it can.
Since enzymes are proteins, changes such as pH level, salinity, and even temperature can denature the proteins rendering them incapable of performing it's function because the shape has been altered.
What happens if you add too much proteinase k to a lysis buffer when performing DNA extraction?
Adding too much proteinase K can lead to excessive digestion of proteins in the sample, potentially reducing the effectiveness of subsequent DNA extraction steps. It can also result in degradation of the DNA itself, as proteinase K is an enzyme that can also digest DNA in high concentrations. It is important to carefully optimize the amount of proteinase K to prevent over-digestion of proteins and DNA.
What two kinds of plants do wheat rusts need to complete their life cycle?
Wheat rusts need two kinds of plants to complete their life cycle: wheat plants, which they infect and reproduce on, and barberry plants, which act as an alternative host where the rust can overwinter and produce spores that then infect wheat plants in the spring.
Where in the gel electrophoresis do you find larger fragments?
The larger the fragments the slower it migrates through the gel. Because it is bigger it takes longer to squeeze through the pores of the gel matrix. So the largest gel fragments will be at the top, closest to where the sample started.
What determines how many amino acids is in a polypeptide?
When a gene is transcribed there is a sequence of RNA bases that was copied from the DNA sequence. The RNA sequence can be exactly the same as the DNA or can be modified more in higher organisms by removing the introns if any. Three RNA bases is a codon. Each codon signifies an amino acid. There is an initiation codon and a terminal codon. So the amino acid sequence is determined by the sequence (multiple of 3 RNA bases) of codons between the initiation codon and termination codon.
What substances are directly involved in photosyntehsis?
The main substances directly involved in photosynthesis are carbon dioxide (CO2), water (H2O), and sunlight. These substances are utilized by plants to produce glucose and oxygen through the process of photosynthesis.
What is the food that contains high amount of vitamin zinc?
Zinc is found in oysters, and to a far lesser degree in most animal proteins, beans, nuts, almonds, whole grains, pumpkin seeds and sunflower seeds.
Other food that contain zinc:
What is Dna replication said to be?
Based on how it occurs, it is said to be 'semi-discontinuous' replication.
What is the chemical use to cause polyploidy?
Colchicine is commonly used to induce polyploidy in plants. It disrupts microtubule polymerization, leading to the formation of cells with double the normal chromosome number. This can result in increased genetic variation and potential for breeding new varieties with desirable traits.
Which of these proteins in mammals show only primary and secondary structures?
Collagen and keratin are examples of proteins in mammals that primarily exhibit only primary and secondary structures. Collagen is known for its triple helix structure, while keratin is a fibrous protein that forms alpha-helices and beta-sheets.
What is chemosynthesis and how is it different from photosynthesis?
Chemosynthesis is the process by which organisms use chemical energy to produce food. This is different from photosynthesis, which is the process by which green plants and some other organisms use sunlight to convert carbon dioxide and water into glucose for energy. Chemosynthesis does not require sunlight and can occur in environments where light is not available, such as deep-sea hydrothermal vents.
Does Benedict's solution reacts with proteins?
Benedict's solution reacts with reducing sugars, not proteins. It is commonly used in biochemical tests to detect the presence of reducing sugars such as glucose. Proteins do not typically react with Benedict's solution.
What hormone is the most important stimulus of epiphyseal plate activity?
The growth hormone is the most important stimulus of epiphyseal plate activity, as it is responsible for stimulating the growth of bones during childhood and adolescence. It acts on the epiphyseal plates to promote bone growth and elongation.
Is calcium bentonite clay and di tri octahedral smectite the same?
No, calcium bentonite clay and di tri octahedral smectite are not the same. Calcium bentonite is a type of clay that contains calcium ions and is commonly used in skincare and wellness products. Di tri octahedral smectite refers to a group of crystalline minerals with specific structural properties, and it is sometimes used in industrial applications or as an additive in certain products, but it is not the same as calcium bentonite clay.
Where can you buy saturated calomel reference electrode?
Saturated calomel reference electrodes can be purchased from scientific supply companies, online retailers that specialize in laboratory equipment, or directly from manufacturers of electrochemical instrumentation. It is important to ensure that the supplier is reputable and provides authentic products to maintain the accuracy and reliability of your measurements.
How do you pronounce hormones?
Hawr-mohn
It sounds like
Hor=Whore
Mone=Moan(like male or females moan during sexual intercourse)
What is the function of the LTH hormone?
At puberty, the hypothalamus produces GnRH (gonadotropin releasing hormone.) GnRH then stimulates production of LH (leutinizing hormone) and FSH (follicle stimulating hormone)which are released by the pituitary gland. In males, LH causes secretion of testosterone and other androgens by the interstitial cells (located in between the seminiferous tubules in the testies.) Testosterone,among others duties, aids FSH in the stimulation of spermatogenesis (production of spermatozoa) and promotes the functional maturation of spermatozoa.
How many oxygen atoms are needed to start photosynthesis reaction?
In the first step of photosynthesis, which is light-dependent, two water molecules are needed to start the reaction. Each water molecule contains two oxygen atoms, so a total of four oxygen atoms are needed.
What are biochemical parameters?
Biochemical parameters are measurable components in the body that provide information about its physiological functions. These parameters can include levels of proteins, enzymes, hormones, and other molecules that help diagnose and monitor health conditions. They are often tested through blood, urine, or other bodily fluids.
Which plant hormones causes fruit to ripen?
Ethylene is the plant hormone responsible for fruit ripening. It is a gaseous hormone that acts as a signal to trigger the ripening process in fruits, leading to changes in color, texture, and flavor. Ethylene is commonly used in the food industry to ripen fruits artificially.
