What are the strands of genetic material floating in a nucleus of a animal cell?
Strands of genetic material floating in the nucleus is chromatin. Cytoplasm is the part of the cell that is between the cell membrane and the nucleus.
Describe two ways in which genetic recombination occurs during meiosis?
The independent orientation of chromosome tetrads in prophase I. Simplified diagram,
FM

Crossing over also in prophase I.
A part of the female chromosome and a part of the male chromosome, aligned together, swap places; genetic material.
What happens to clones after they are cloned?
Cloning can make all the descendants of a particular line susceptible to the same possible defects and mutations.
How do scientists make clones?
The first step in using the polmerase chain reaction method to copy a gene is to heat a piece of DNA which separates its two strands. Then, as the DNA cools, primers bind to the single strands. Next, DNA polymerase starts copying the region between the primers. These copies can serve as templates to make still more copies.
What is the importance of gene cloning?
Genetic cloning allows us to study genetic disorders in a lab environment. we can perform experiments on these cloned cells without having to endanger the patient themselves. these clones aren't humans, you can't even see them without a microscope most of the time. By performing these experiments we learn about the different processes that occur within the cell. and the more we learn about these processes the more we can do to prevent disorders that occur due to malfunctions in these processes.
What are the Feature of genetic code?
it is made of a sequence of nucleotides:in DNA or RNA, these nucleotides are adenine, guanine, cytosine, and uracil where it determines the specific amino acid sequence in the proteins,but is the biochemical of heredity and nearly universal in all organisms... DNA transfers and forms a code.
How is genetic engineering used in human growth hormone therapy?
Growth hormones are something that are fed animals at most slaughter houses or dairy houses. This means that the meat, poultry or dairy you are consuming is not organic. Growth hormones make cows or chickens provide more meat, poultry or dairy by growing them artificially.
A virus that stores its genetic information as RNA is called?
It is called a Retrovirus HIV is an example of a Retrovirus
Whether enzyme is bigger or DNA is bigger in molecular size and how do we conclude that?
enzyme is nothing but the protein which is formed from DNA by translation through transcription of a particular region of the DNA . so obviously the DNA is larger than the enzyme in molecular size.
What is the controversy of cloning humans?
The controversy surrounding human cloning is an ethical issue. People wonder if humans have the right to create other humans and if humans do have that right, do they also have the right to take life away? The controversy is over life and death and who has the power to control them.
ADD stands for Attention Deficit Disorder.
It is primarily passed down through genetics. Most parents find out they have ADD or OCD (as they are opposites of one another) as a result of their child's diagnosis.
See "difference between ADD and OCD".
How many divisions occur in meiosis?
Meiosis does in fact divide twice, once in meiosis I (cytokinesis) and meiosis II (cytokinesis) basically it divides into four daughter cells at the end of meiosis. Two from meiosis I and four in meiosis II
Why do you clone humans and why?
No human has yet been cloned. With the exception of identical twins.
Where can a genetic counselor work?
Geneticists are specialists in genetics and genetics related problems. Genetics refers to the study of hereditary i.e. the passage of information from one generation to another. Experiments are carried out in labs so as to pindown the role of specific gene in a given condition. They also do studies relating to genetic disorders caused by mutation and various other regions and methods of overcoming that using gene therapy and other modes of better management.
What Material in nucleus that contains genetic information?
DNA (deoxyribonucleic acid) contains the genetic information inside cells. The genetic information itself is a code of letters out of 4 possible nitrogen bases (A,T,G,C) eg. ACGTATGCATGGT. A gene is a portion of this code that has information for the construction of one type of protein chain.
What are the goals for human genetic engineering?
First and foremost, there is currently no known research anywhere in the world with the purpose of growing genetically engineered humans. There are discussions about the benefits of such technology, as this would allow us to eradicate genetically inherited diseases such as cystic fibrosis and haemophilia. Genetically engineered human embryos could be used for research to understand how and why defects occur during development of a baby in the womb.
Theoretically, it could allow modifying most biological traits of the human body. Some people consider this an advantage, but across the world it is most commonly considered unacceptable and/or undesirable.
Genetically engineered human cells (as opposed to entire humans) are already in use to treat severe genetic blood diseases. For this purpose, haemopoietic stem cells are taken from the patient's bone marrow. They are then genetically modified to correct the mutations that cause the blood disease. Finally, the patient's bone marrow is eradicated and the treated haemopoietic stem cells are injected. These stem cells then restore the bone marrow to a healthy state. Similar technologies are being developed to cure other organ-specific genetic defects.
Arguments in favor of Animal Cloning?
The one benefit of animal cloning that will have the biggest impact on our environment is that with the technology of cloning, we can now preserve endangered breeds and species.
The genetic code of a DNA molecule is determined by a specific sequence of WHAT?
A gene is a sequence of nucleotide which is composed of a nitrogenous base(adenine,guanine,thymine & cytosine in case of DNA and thymine is replaced by uracil in case of RNA),a sugar residue(de-oxyribose in DNA & ribose sugar in RNA) and a phosphate group.
How is genetic information passed down from one generation to the next in plants?
Genetic information in plants is passed on from one generation to the next just like in any other living organisms. This is through genes. Genes are parts of the chromosomes whose greater part is the DNA. Through the process of meiosis (which is cell division) the number of chromosomes in a cell is halved. this leads to gametegenesis which is the formation of gametes. each resulting cell with half the number of chromosomes as the original cell carries all the genes.
