Identify the type of RNA which is not involved in gene expression
|
|
rRNA
|
|
|
mRNA
|
|
|
tRNA
|
|
|
hnRNA
|
Explanation:
Detailed explanation-1: -This led to the conclusion that HnRNA is directly involved in rRNA transcription (Schmid & Sekeris, 1973a). Another relevant finding involved the effects of glucocorticoids on RNA synthesis. It is known that these steroid hormones induce both HnRNA and rRNA synthesis (Karlson, Doenecke & Sekeris, 1975).
Detailed explanation-2: -Thus, mRNA, tRNA and rRNA are involved in gene expression.
Detailed explanation-3: -∙ Heterogeneous nuclear RNA or hnRNA is a term that encompasses various types and sizes of RNAs that are found in the eukaryotic cell nucleus.
Detailed explanation-4: -Assertion :Hn mRNA is larger than mRNA. Reason: HnRNA has nontranslating introns and more exons than required for translation.
