Q. Explain all the process of transcription?

❤️THANKS❤️​

Answer 1

Ello ✌️

here is ur answer...

Transcription is the process in which a gene's DNA sequence is copied (transcribed) to make an RNA molecule. RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination.

Transcription involves four steps:

Initiation:- The DNA molecule unwinds and separates to form a small open complex.

Elongation:- RNA polymerase moves along the template strand, synthesising an mRNA molecule.

Termination:- In prokaryotes there are two ways in which transcription is terminated.

Answer 2

Answer:

Transcription is the process of Copying of Gene's sequence to make RNA molecule.

There are four steps of Transcription

Initiation:- In this the DNA molecule separate to form small open complex .RNA polymerase binds to the promotor of the template stand.

Elongation:- RNA polymerase moves along the template stand synthesise an MRNA molecule . In prokaryote RNA polymerase is a holoenzyme consisting of number of sub units including sigma factor that recognize promotor.

Termination:- In prokaryote , there are two ways in which transcription is terminated. In Eukaryotes, termination is more complicatedwhich involve addition of additional adenine.

Processing:-After transcription the RNA molecule is processed in number of ways .
