Question 8

Which strand antisense or sense strand of DNA is transcribed?

Answer 8

Antisense strand

Question 9

Answer 9

Coding strand of DNA

Question 10

At what nitrogen bases does transcription begin?

Answer 10

TATA box

Question 11

What is tRNA activated by?

Answer 11

tRNA activating enzyme- uses ATP

Question 12

What are the main components of ribosomes?

Answer 12

Small subunit
mRNA binding site
Two tRNA binding sites
Large subunit

Question 13

Polysomes

Answer 13

Makes protein synthesis more efficient

Question 14

What are the steps of translation?

Answer 14

1. Initiation
2. Elongation
3. Termination
4. Translocation

Question 15

Translation

1. Initiation

Answer 15

Ribosome binds with mRNA; start codon; first tRNA molecules Are brought in

Question 16

Translation

2. Elongation

Answer 16

Peptide bond is formed between amino acids; polypeptides made

Question 17

Translation

3.translocation

Answer 17

Ribosome releases tRNA and moves along mRNA to the next codon; this elongates the polypeptide further

Question 18

Translation

4. Termination

Answer 18

Stop codon reached; polypeptide is released; ribosome picks up new mRNA strand

Question 19

Exocytosis

Answer 19

Proteins produced in bound ribosomes (rough ER) are for export out of cell
