medium
નીચેનામાંથી કયો $RNA$ પ્રાણીકોષમાં સૌથી વિશેષ હોવો જોઈએ?
A
$tRNA$
B
$mRNA$
C
$miRNA$
D
$rRNA$
(NEET-2017)
Solution
(d) : $rRNA$ (ribosomal $RNA$) is the most abundant of all types of $RNA\ (70-88\%)$. Hence, it will be present in highest amount. Percentage of $tRNA$ and $mRNA$ is $15\%$ and $25\%$ respectively. $miRNA$ (micro $RNA$) are $21-22\ bp$ long $RNA$ that bring degeneration of $mRNA.$
