1
Q

Sentence 1

A

The first stage of protein synthesis is transcription.

2
Q

Sentence 2

A

This occurs in the nucleus of the cell.

3
Q

Sentence 3

A

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

4
Q

Sentence 4

A

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.

5
Q

Sentence 5

A

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.

6
Q

Sentence 6

A

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

7
Q

Sentence 7

A

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

8
Q

Sentence 8

A

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