Protein synthesis - Translation

Question 1

Sentence 1

Answer 1

This will start the second stage of protein synthesis called translation.

Question 2

Sentence 2

Answer 2

This occurs in the cytoplasm of the cell.

Question 3

Sentence 3

Answer 3

A small subunit of the ribosome will attach to the start codon of mRNA, which will always be AUG.

Question 4

Sentence 4

Answer 4

The first tRNA molecule will bring a specific amino acid to the ribosome, and add it to the polypeptide chain.

Question 5

Sentence 5

Answer 5

The ribosome will match the anticodon, which is the set of 3 nucleotides on tRNA that code for a specific amino acid, to the codon on mRNA.

Question 6

Sentence 6

Answer 6

Then the large subunit of the ribosome will fit over the small subunit of mRNA.

Question 7

Sentence 7

Answer 7

The mRNA strand will be read off by the ribosome like a ticker tape.

Question 8

Sentence 8

Answer 8

Weh the stop codon is reached, the ribosome will detach, and the protein is fully produced.

Question 9

Sentence 9

Answer 9

When you are deciding the amino acids in a chain, you will need to read off the mRNA chain, and use the codon dictionary.
