Question:

The high rate of diversification of HIV strains inside a host is a result of (SELECT ALL THAT APPLY):

1. High mutation rates in the HIV itself.

2. Strong and varying selection forces caused by hypermutation of antibody genes in the lymphocytes.

3. Errors in transcribing the viral RNA from the host DNA.

All the above options are correct.

Explanation:

According to research, Retroviral cultures evolve rapidly to fit the dynamic nature of their environs.

It is also established that errors in replication can provide the basis for diversity.

Cheers!

hope this !

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
