Answer:
Somatic hypermutation is a process in which point mutations build up in the antibody V-regions of both the heavy and light chains.
This process occurs at rates that are about 106-fold higher than the background mutation rates observed in other genes.
It allows B cells to mutate the genes that they use to produce antibodies. This then ensures the B cells to produce antibodies that are better able to bind to bacteria, viruses and other infections.
Answer:
8 amino acids differ between the monkey and the human sequences.
Explanation:
The genome mapping has now made it possible to identify genes that are present on a chromosome. Genetic mapping is also being used to study the similarities between organisms which has helped a lot to understand the evolutionary history among organisms and to assemble the phylogenetic lineages.
Scientists have found the genome of the monkeys to be the most similar to humans with a difference of just 8 amino acids between them. Hence, justifying the hypothesis that humans have evolved from monkeys.
Explanation:
A cryosphere is just a hydrosphere but it's frozen in some way. glaciers, ice caps, and icebergs are cryospheres (frozen bodies of water).
It converts Energy to food!
Hope this helps
