343332 Select the incorrect option
A. RNA polymerase polymerises in a template depended fashion following the rule of complementarity
B. Once the polymerases reaches the terminator region, the nascent RNA falls off, so also the RNA polymerase.
C. The RNA polymerase is only capable of catalysing the process of termination.
D. RNA polymerase associates transiently with initiation-factor \((\sigma)\) and termination-factor \((\rho)\) to initiate and terminate the transcription, respectively.

BIOXII06: MOLECULAR BASIS OF INHERITANCE

343333 During transcription, in eukaryotes, there are two additional complexities

1 There are at least two RNA polymerases in the nucleus, the primary transcripts contain both the exons and the introns.
2 There are at least three RNA polymerases in the nucleus, the secondary transcripts contain both the exons and the introns.
3 There is only one RNA polymerases in the nucleus, the primary transcripts contain both the exons and the introns.
4 There are at least three RNA polymerases in the nucleus, the primary transcripts contain both the exons and the introns.
