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.
What initiation and termination factors are involved in transcription in Eukaryotes ?
Which of the following is responsible for transcription of $t-RNA$ and $snRNAs$
If the sequence of one strand of $DNA$ is written as follows:
$5'- ATGCATGCATGCATGCATGCATGCATGC-3'$
Write down the sequence of complementary strand in $5^{\prime} \rightarrow 3^{\prime}$ direction
$A$ - The process of splicing represents the dominance of $RNA$ word.
$R$ - The presence of introns is reminiscent of antiquity.
$m\, -$ $RNA$ is formed by
