transcription

Question 1

what is transcription

Answer 1

Transcription is the process by which a section of DNA acts as a template,

for the creation of a complementary mRNA strand

Question 2

what does RNA polymerase do

Answer 2

attaches to the DNA double- helix at the beginning of a gene

Question 3

2nd step transcription

Answer 3

hydrogen bonds between the two DNA strands break, separating the strand, and the DNA molecule uncoils

Question 4

3rd step transcription

Answer 4

one of the strand is used as a template strand to make an mRNA copy

Question 5

4th step transcription

Answer 5

RNA polymerase lines up free RNA nucleotides alongside the template strand

because of complementary base pairing the mRNA strand is complementary to the DNA template strand

Question 6

5th transcription

Answer 6

once the RNA nucleotides have paired up with bases on the DNA template strand they are joined together forming mRNA molecule

Question 7

6th transcription

Answer 7

RNA polymerase moves along the DNA, separating the strands and forming the mRNA strand

Question 8

7th transcription

Answer 8

once the RNA polymerase has passed by hydrogen bonds REFORM between uncoiled strands of DNA, coiling back into a double helix

Question 9

8th transcription

Answer 9

when mRNA reaches a stop codon it stops making mRNA and detaches from the DNA

Question 10

9th (LAST STEP) transcription

Answer 10

the mRNA moves out of the nucleus through a nuclear pore

and attaches to a ribosome on the cytoplasm.

Question 11

1st step transcription

Answer 11

RNA polymerase attaches to the DNA double helix at the beginning of a gene.
