A) \[\sigma \]-subunit
B) \[\beta \]-subunit
C) \[\text{ }\!\!\rho\!\!\text{ -}\]factor
D) spliceosome
Correct Answer: A
Solution :
RNA polymerase consists of a core enzyme, with subunits \[(\alpha ,\alpha ,\beta ,\beta ,\omega )\]and a sigma \[(\sigma )\]factor. The sigma factor initiates transcription of mRNA on the DNA template and directs the binding of the enzyme to the promoter region. The core enzyme continues transcription.You need to login to perform this action.
