Question: need a and b please 4 chemokines are receptor proteins...
Need A and B please. 4. Chemokines are receptor
proteins found in cell membranes of immunecells. The C-C chemokine
receptor-5 protein is a receptor that allons the HIV-1 virus to
enter immune cells and is encoded by the CCR5 gene. A mutant allele
has a 32 base pair deletion that makes the receptor protein
nonfunctional and is coded for by the mutant allele A32 The normal
allele is CCR5-1 (w). Individuals who are A32/432 areresistant to
HIV-1 infection, those who are heterozygous w/A32 are still
affected by HIV-1 but the progression to AIDS is slower, and ww
individuals are susceptible to HIV-1.A study of 548 individuals in
Italy found the following genotypespresent in the population:
w/w 491W1432 = 51432/432 =6
b. What are the allelic frequencies of w (p) and A32 (q)?
c. What are the expected genotypic frequencies if this population is at Hardy-Weinberg equilibrium?
