The sigma-70 subunit

#SCPH28 | Zoology
  1. increases the affinity of the core polymerase for nonpromoter sequences.

  2. decreases the affinity of the core polymerase for specific promoter sequences.

  3. is responsible for transcribing many genes.

  4. is associated with a holoenzyme, enabling the formation of more stable complexes.

 In a human population, the gene frequencies of the alleles for the ABO system are as follows:

A = 29%                         B = 7%                                    0=64%

Assuming complete random mating and Hardy-Weinberg equilibrium,

What are the blood type A frequencies in this population?
