If one strand of $DNA$ has the nitrogenous base sequence as $ATCTG$, what would be the complementary $RNA$ strand sequence?
$TTAGU$
$UAGAC$
$AACTG$
$ATCGU$
$DNA$-dependent $RNA$ polymerase catalyses transcription on one strand of the $DNA$ which is called the
Explain (in one or two lines) the function of the followings:
$(a)$ Promoter
$(b)$ $tRNA$
$(c)$ Exons
Reverse transcriptase:
In eukaryotes, $mRNA$ is synthesized with the aid of
