Molecular Basis Of Inheritance Question 5

Question: What is the role of RNA polymerase III in the process of transcription in Eukaryotes?

(1) Transcription of rRNAs (28S, 18S and 5.8S)

(2) Transcription of tRNA, 5 srRNA and snRNA

(3) Transcription of precursor of mRNA

(4) Transcription of only snRNAS

Show Answer

Answer: (2) Transcription of tRNA, 5 srRNA and snRNA

Explaination-

4 Types of RNA:

  • Messenger RNA (mRNA) mRNA is translated into a polypeptide.

  • Transfer RNA (tRNA) tRNA will bind an amino acid to one end and has an anticodon on the other.

  • Ribosomal RNA (rRNA) Ribosomal RNA (rRNA) helps facilitate the bonding of amino acids coded for by the mRNA.

  • Micro RNA (miRNA)
