Vedclass · Answer

(A) $1$. Tomato cells have a cell wall made of cellulose,which must be broken down by cellulase to release the cellular contents.$2$. Proteins associated with the genetic material must be removed using protease.$3$. To isolate pure $RNA$,the $DNA$ present in the cell must be degraded. Deoxyribonuclease $(DNase)$ is an enzyme that specifically digests $DNA$ but does not affect $RNA$.$4$. Therefore,treating the mixture with $DNase$ ensures that $DNA$ is removed,leaving $RNA$ intact for extraction.$5$. Both the Assertion and the Reason are correct,and the Reason provides the correct explanation for why $DNase$ is used in the extraction process.

$A$: To extract $RNA$ from tomato cells,it must first be treated with cellulase,protease,and then deoxyribonuclease.
$R$: Deoxyribonuclease will digest $DNA$ while $RNA$ will be intact.
