Question
1. This step occurs in the nucleus.
a. posttranslational processing
b. Posttranscriptional processing
2. This step involves the placement of a cap and tail to the mRNA molecule.
a. Posttranscriptional processing
b. posttranslational processing
3. This step involves the joining of 2 or more amino acid chains with one another.
a. Posttranscriptional processing
b. posttranslational processing
4. This step involves the incorporation in exons and the removal of introns from the resultant molecule.
a. post translational processing
b. Posttranscriptional processing
5. This step occurs in the cytoplasm.
a. Posttranscriptional processing
b. posttranslational processing
Explanation / Answer
Ans1)b
Posttranslational processing occurs in nucleus because the mRNA formed in nucleus undergoes modification and then after modified mRNA is then released into cytoplasm.
Ans2)a
Post transcriptional processing involves the addition of a cap and a tail to the mRNA
Ans3)b
After translation the chains of amino acids are joined together so as to form a peptide.
Ans4)a
Post translational processing involves the removal of introns from mRNA
Ans5)b
Post translational processing occurs in the cytoplasm of cell.The protein chain undergoes modification.
