How do immunoglobulin genes code for a seemingly infinite variety of antibodies?

Biology
1 answer:
Ivanshal [37]4 years ago
6 0
<span>Answer: Think of DNA-there are only 4 bases, but different combinations give infinite possibilities. And the same for amino acids and proteins. Immunoglobulins work on a similar principle. Different VDJ segments are combined for the heavy chain of an antibody. Different VJ segments are combined for the light chain. Other ways: Random nucleotides may be added or removed between the gene segments. There are also different combinations of light and heavy chains. Antibodies can be any of the 5 isotypes: IgA, IgM, IgG, IgE, IgD. I'm not going to go into detail as this answer would take too long to write. Do some literature searching on B cells, V(D)J recombination, RAG genes, class switching.</span>

The human genome comprises about 3 x 109 base pairs of DNA, and no two humans, other than identical twins, ever have been or wil
arsen [322]

Answer:

The correct answer is C.

Explanation:

The amount of genetic variation in two humans is 0.1 percent of their genome. Human genetic variation refers to the biological difference that exists in the human population.

The genetic variation in humans and apes genome is about 4 percent which is 35 million differences in a single nucleotide.

The genetic variation between apes and humans (Homo sapiens), according to scientists includes gene expression differences, variation in the transportable elements and type and number of repetitive genomic DNA transportable elements, the difference in the gene sequence, single nucleotide polymorphic, etc.

According to research, 97 percent of humans and orangutans genomes are identical. Based on evolution, among all apes, the orangutans are very special as it has been stable for the past 15 million years.

Therefore, is the genetic variation between humans and orangutans is the greatest.
