Question

Q1 : put the following of protein synthesis transcription steps in the correct order

A- the RNA-pol stops transcribed when reaching a repetitive sequences of T nucleotides

B- the 3"segments of the nascent RNA hybridizes with the DNA template , and its 5'end extends out the transcription

C- after DNA transcription passes , the two DNA strands reform

D- RNA-pol start move on the DNA template melting and unwinding the double helix

F- the transcript RNA strand is released

G- synthesize complementry mRNA in the 5' to 3' direction

H- RNA pol recognizes the promoter

i - RNA polymerase moves down on the DNA template from 3' to 5' direction adding free NTPs sequentially

Answer 1

1- RNA polymerase recognizes the promoter

2- RNA-pol start move on the DNA template melting and unwinding the double helix

3- Synthesize complementary mRNA in the 5' to 3' direction

4- The 3"segments of the nascent RNA hybridizes with the DNA template, and its 5'end extends out the transcription

5- RNA polymerase moves down on the DNA template from 3' to 5' direction adding free NTPs sequentially

6- After DNA transcription passes, the two DNA strands reform

7- The RNA-pol stops transcribed when reaching a repetitive sequences of T nucleotides

8-The transcript RNA strand is released
