Question

what are the functions of methylated guanine cap and poly-A tail in mature mRNA ​

Answer 1

Methylated Guanine cap helps in binding of mRNA to smaller ribosomal sub-unit during initiation of translation.Poly-A tail provides longevity tomRNA's life. Tail length and longevity of mRNA are positively correlated.

Answer 2

1)Methylated guanine cap helps in binding of Mr any two smaller ribosomal subunit during initiation of translation .

2) poly A tail provide

longitivity to mRna life.
