NEETBiologyMolecular Basis of InheritanceMCQ+4 / −1
Which of the following RNAs is not required for the synthesis of protein?
  1. A
    siRNA
  2. B
    mRNA
  3. C
    tRNA
  4. D
    rRNA
View written solutionFree

Correct answer: A

siRNA mainly protect the cell from exogenous mRNA attacks. It degrades the growing mRNA and stop gene expression. It is highly specific and reduces the synthesis of particular proteins by reducing the translation of specific messenger RNAs. Hence, siRNA is not required for protein synthesis but is used to reduce its synthesis.

mRNA is messenger RNA that carries genetic information provided by DNA.

tRNA carries amino acids to the mRNA during translation.

rRNA is structural RNA that forms ribosomes which are involved in translation.
