Why might the knoblike proteins on the outer surface of hiv hold a key to the production of a vaccine against aids?

Biology
1 answer:
Nataly_w [17]3 years ago
4 0

This is because the GP120 protein of the HIV virus that forms the ‘knob’ is essential for the infection of CD4 cells of the immune system by the virus. The glycoprotein is, therefore, a good target for vaccines especially since the molecule is highly conserved because most mutations in the region could be highly deleterious to the virus.

Umnica [9.8K]
If I assume that random segregation of chromosomes takes place during spermatogenesis and all sperms are viable then I will take the male through meiosis.
The three chromosomes are +, +, ey
Then you double them into sister chromatids which is ++, ++, eyes.
If I consider all possible alignments during metaphase as, the three homologous pairs and gather at the metaphase plate.
Remember that any two of the three pairs will join together and odd pair out will line up at the metaphase plate with no partner pair.
There are three different arrangements which are possible for the three homologous pairs. 
Two of the three possible arrangements will segregate and make two sperm with +ey and two sperm with +. The other arrangement will segregate and make two sperm with ++ and two sperm with ey.
When meiosis is being done, then the sperm genotypes and their proportions are, 
1/3+ey, 1/3+, 1/6++, 1/6ey
