Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
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.
A
Both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
B
Both Assertion and Reason are true but the C Reason is not the correct explanation of the Assertion.
C
Assertion is true but Reason is false.
D
Both Assertion and Reason are false
Explanation: 

Detailed explanation-1: -The 5’ and 3’ untranslated regions (UTRs) are mRNA domains that control critical post-transcriptional gene regulation processes. As regions that are transcribed, but seldom translated, the 5’ and 3’UTRs contain a myriad of regulatory elements involved in pre-mRNA processing, mRNA stability, and translation initiation.

Detailed explanation-2: -The untranslated regions (UTRs) in mRNA play critical role of regulating the stability, function, and localization of mRNA. The 3’-UTRs of mRNA also serve as templates for miRNA binding that regulates the turnover and/or function of the mRNA.

Detailed explanation-3: -The UTRs are present at both 5 end (before start codon) and at 3-end (after stop codon). They are required for efficient translation process.

Detailed explanation-4: -The UTRs are present at both the 5’-end (before the start codon) and the 3’-end (after the stop codon). They are required for an efficient translation process.
