Assertion is correct,but Reason is incorrect.

Vedclass · Answer

(C) The Assertion is incorrect because the $5S$ $rRNA$ is a component of the large ribosomal subunit ($60S$ in eukaryotes or $50S$ in prokaryotes),but it does not specifically provide the binding site for $tRNA$. The $tRNA$ binding sites ($A$,$P$,and $E$ sites) are formed by the complex structure of $rRNA$ and ribosomal proteins within the ribosome,not specifically by the $5S$ $rRNA$ alone.The Reason is correct. $tRNA$ (transfer $RNA$) is indeed known as soluble $RNA$ $(sRNA)$ because it remains in the supernatant after centrifugation. It also contains unusual or modified bases such as pseudouridine,dihydrouridine,and methylguanosine,which are characteristic of its structure.

$A$ : $5S$ $rRNA$ and surrounding protein complex provides binding site of $tRNA$.
$R$ : $tRNA$ is soluble $RNA$ with unusual bases.
