In bacteria, binding of _________ factor to the RNA polymerase increas

1.	In bacteria, binding of _________ factor to the RNA polymerase increases its affinity for promoter sites in the DNA.(a) alpha(b) sigma(c) rho(d) betaThis question was addressed to me in an interview.My question is from Gene Expression topic in portion Gene Expression of Cell Biology
Answer» RIGHT answer is (b) sigma The explanation: In BACTERIA, binding of the sigma FACTOR to RNA polymerase enzyme increases the latter’s AFFINITY for promoter sequences in the DNA.
