Protein synthesis - Transcription

Question 1

Sentence 1

Answer 1

The first stage of protein synthesis is transcription.

Question 2

Sentence 2

Answer 2

This occurs in the nucleus of the cell.

Question 3

Sentence 3

Answer 3

During this stage, the enzyme RNA polymerase will read off the template strand of DNA.

Question 4

Sentence 4

Answer 4

This enzyme will grab free nucleotides and add them to the mRNA chain by complimentary base pairing; to where guanine on DNA would pair with cytosine, and adenine on DNA would pair with uracil.

Question 5

Sentence 5

Answer 5

The enzyme RNA polymerase will read the triplet code which is the set of 3 nucleotides on DNA that code for an amino acid, and produce the codon, which is the set of 3 nucleotides on mRNA that code for an amino acid.

Question 6

Sentence 6

Answer 6

Whe the enzyme RNA polymerase reaches the end of the gene, it and the mRNA will detach.

Question 7

Sentence 7

Answer 7

The two strands of the DNA molecule will reform by hydrogen bonding.

Question 8

Sentence 8

Answer 8

The mRNA molecule will leave the nucleus through the nuclear pores.
