Transcription

Question 1

What does RNA polymerase form and how does it do it?

Answer 1

Forms mRNA strand (template) by joining nucleotides together

Question 2

What is RNA Polymerase responsible for?

Answer 2

Transcription as it moves along the gene, unwinding and opening the DNA strand

Question 3

What are non coding regions on mRNA called?

Answer 3

Introns

Question 4

What are coding regions on mRNA called?

Answer 4

Exons

Question 5

What is the primary transcript called after the non coding sections have been removed?

Answer 5

Mature transcript

Question 6

How can a single mature transcript of mRNA produce many different proteins?

Answer 6

Alternative splicing.

Question 7

State which each four sides of a tRNA molecule can bind to

Answer 7

One side binds to mRNA (anti codeon)
2nd side binds to ribosome
3rd side binds to a specific amino acid
4th side binds to enzymes controlling the process

Question 8

How does the mature mRNA transcript exit the nucleus?

Answer 8

Via a nuclear pore.

Question 9

Where do mature mRNA transcripts go once they exit the nucleus?

Answer 9

To a ribosome in the cytoplasm to be translated
