Assertion : An mRNA has both initiation ...

Assertion : An mRNA has both initiation codon and termination codon.
Reason : It specifies only a single polypeptide or number of them.

A

If both the assertion and the reason are true and the reason is a correct explanation of the assertion

B

If both the assertion and reason are true but the reason is not a correct explanation of the assertion

C

If the assertion is true but the reason is false

D

If both the assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
B
mRNA has initiation codon or start codon for initation of protein synthesis i.e. AUG in both prokaryotes and eukaryotes and termination codon i.e. UAA, UAG and UGA that stop protein synthesis.
mRNA may be monocistronic that single gene code for single polypeptide chain or polycistronic a single gene code for many polypeptide chain

Assertion :- UGG is a chain termination codon. Reason : It does not code any amino acid.

The initiating codon AUG specifies for

Assertion : Untranslated regions are sequences of RNA before initiation codon and after termination codon. Reason : Untranslated regions provide stability to mRNA and also increase translational efficiency.

In mRNA , AUG is the initiating codons and UAA, UAG and UGA are terminatinng codona . Therefore, the polypeptide cannot be synthesised beyond any of these triplets to the end of mRNA, then which one of the following mRNA can be translated completely?
