Question

In a mRNA molecule, untranslated regions (UTRs) are present at (A) 5' - end (before start codon) (B) 3' - end (after stop codon) (C) both (a) and (b) (D) 3' - end only

mRNA has some additional sequences that are not translated and are referred as untranslated regions (UTRs). 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.

Q. In a $m RN A$ molecule, untranslated regions $(U TR s)$ are present at

$5^{'}$ - end (before start codon)

$3^{'}$ - end (after stop codon)

both (a) and (b)

$3^{'}$ - end only

$m RN A$ has some additional sequences that are not translated and are referred as untranslated regions $(U TR s)$ . The $U TR s$ are present at both $5^{'}$ -end (before start codon) and at $3^{'}$ -end (after stop codon). They are required for efficient translation process.

Q. In a mRNA molecule, untranslated regions (UTRs) are present at

5′ - end (before start codon)

3′ - end (after stop codon)
