Bio quesitons

1. During translation, how does
the initiator tRNA (containing a covalently bound methionine)
differ from all subsequent incoming aminoacyl tRNAs?

A. Only the initiator tRNA starts out in the P site of the
ribosome

B. Only the initiator tRNA starts out in the A site of the
ribosome

C. Only the initiator tRNA does not bind to a codon in the
mRNA

D. The Met linked to the initiator tRNA is not added to the
growing protein chain

2. A mutation in DNA changes an
adenine to a guanine. This adenine was the A in the ATG of encoding
a start codon. What process or processes would this mutation
impact?

A. Initiation of both transcription and translation

B. Only initiation of transcription

C. Only initiation of translation

D. Neither initiation of transcription nor translation

3. What happens in the
translocation step of translation elongation?

A. Ribosome moves along the mRNA by a distance of 1 codon

B. A tRNA moves along the mRNA by a distance of 1 codon

C. The growing peptide chain moves to a tRNA in the E site

D. A and B are correct

E. A, B, and C are correct

4. Val-tRNAVal is the tRNA that carries valine to the ribosome
during translation. Which of the following sequences gives an
appropriate anticodon for this tRNA?
A. CAU
B. AUC
C. UAC
D. GUG

Give me the right answer for each question and EXPLAIN WHY THAT
ANSWER CHOICE IS CORRECT AND OTHERS ARE INCORRECT.

Thank you!
