Question

RNA polymerase contains multiple polypeptide units. For initiating RNA synthesis it requires (A)  σ -subunit (B)  β -subunit (C)  text ! !ρ ! ! text - factor (D) spliceosome

Tardigrade Admin · Accepted Answer

RNA polymerase consists of a core enzyme, with subunits (α ,α ,β ,β ,ω) and a sigma (σ ) 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.

spliceosome

RNA polymerase consists of a core enzyme, with subunits $(α, α, β, β, ω)$ and a sigma $(σ)$ 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.
