What are the functions of $(i)$ methylated guanasine cap, $(ii)$ poly $-A$ “tail” in a mature on $RNA $ ?
What are the functions of $(i)$ methylated guanasine cap, $(ii)$ poly $-A$ “tail” in a mature on $RNA $ ?
Methylated Guanine cap helps in binding of $mRNA$ to smaller ribosomal sub-unit during initiation of translation. Poly-$A$ tail provides longevity to $mRNA's$ life. Tail length and longevity of $mRNA$ are positively correlated.
