- 4.
![The tRNA that is base pairing with the codon is in the]( "The tRNA that is base pairing with the codon is in the")
The tRNA that is base pairing with the codon is in the- A.
A site
- B.
P site
- C.
E site
- D.
None of the above
- 5.If the anticodon is 5'AGC3' then the codon is
- A.
5'UCG3'
- B.
5'TGC3'
- C.
5'AGC3'
- D.
5'GCU3'
- 6.If the anticodon is 5'AGC3' then the amino acid attached to the codon is (Use your codon table)
- A.
Cys
- B.
Gly
- C.
Ala
- D.
A stop codon
- 7.A section of DNA is 5' AAA TTT CAT 3' If this is transcribed and translated, the resulting amino acid sequence is
- A.
LYS PHE HIS
- B.
PHE LYS VAL
- C.
MET LYS PHE
- D.
MET PHE LYS
- 8.The DNA in the section above changes to 5' TTA TTT CAT 3' If this is transcribed and translated, the resulting amino acid sequence will be (compared to the sequence in the qeustion above) (Use your codon table) The amino acid sequence in the previous question was MET LYS PHE
- A.
Have one less amino acid
- B.
Have one more amino acid
- C.
Have the same number of amino acids,but one will be different
- D.
The amino acids will not change at all
- 9.An mRNA that has 1200 nucleotides can code for a protein of this many amino acids
- A.
1200
- B.
400
- C.
3600
- D.
None
- 10.Deleting a nucleotide will
- A.
Have no affect on the amino acid sequence since a codon is 3 letters
- B.
Will change all amino acids in the protein
- C.
Will change amino acids that are coded 3' to the deletion
- D.
Will change amino acids that are coded 5' to the deletion
- 11.The muscular dystrophy gene has 97 exons, therefore it has this many introns:
- A.
97
- B.
96
- C.
98
- D.
No gene can have that many introns
