Enzyme responsible for DNA chain elongation is

Q. The following nucleotides is used for elongation of RNA chain by RNA polymerase except

Q. DNA polymerase enzyme is responsible for the synthesis of

Q.

The paragraph below gives a description about transcription. Which is the correct description among them? (a) Enzyme involved in transcription is RNA polymerase-II, which consists of 5 polypeptides α, β, β’, σ and ω. Core enzyme recognizes promoter site while σ factor takes part in chain elongation. (b). Initiation starts with help of core enzymes of RNA polymerase enzyme. (c) Elongation is done by σ factor, which moves along the sense strand. (d) In prokaryotes, termination is done by rho factor while in eukaryotes; poly A tail is responsible for termination at 3’.

Q. Name a few enzymes involved in DNA replication other than DNA polymerase and ligase. Name the key functions for each of them.

Q. In eukaryotes, which enzyme catalyzes the formation of 5S rRNA?
