During transcription which end of the new RNA molecule protr

During transcription, which end of the new RNA molecule protrudes from the RNA polymerase?

Select one:

a. the 5\' end

b. the 3\' end

c. the amino group

d. the carboxy group

Solution

ANS: A. The 5\' end.

During transcription, the 5’ end new RNA molecule protrudes from the RNA polymerase

In transcription RNA molecule moves from 3’ end of template strand, it creates the new RNA strand that grows in 5’ to 3’ direction. It is mainly happens due to the antiparallel nature of the RNA, so the new strand must be antiparallel to the template strand.
