What role does messenger $RNA$ play in the synthesis of proteins?
It catalysis the process.
It translates the genetic code to a specific amino acid.
It provides the genetic blue print for the protein.
It modifies messenger $RNA$ molecules prior to protein synthesis.
In eukaryotes, $mRNA$ is synthesized with the aid of
Explain (in one or two lines) the function of the followings:
$(a)$ Promoter
$(b)$ $tRNA$
$(c)$ Exons
Prokaryotic transcription mechanism requires involvement of only one polymerase type and
$(a)$ It occurs in cytoplasm only
$(b)$ It is often coupled with translation
$(c)$ It does not require splicing but capping is essential
If there are $81\; million$ bases in $RNA$ of human cell, then calculate the total number of introns present in $cDNA$
If one strand of $DNA$ has the nitrogenous base sequence as $ATCTG$, what would be the complementary $RNA$ strand sequence?
