Match List - I with List - II.
| List – I Name | List – II Functions |
|---|---|
| (A) mRNA | (I) amino acid carrier |
| (B) rRNA | (II) structural and catalytic role during translation |
| (C) tRNA | (III) gene |
| (D) cistron | (IV) template for protein synthesis |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A)-(IV), (B)-(II), (C)-(I), (D)-(III)
(A) mRNA — this matches (IV) template for protein synthesis. mRNA carries the code read during translation.
(B) rRNA — this matches (II) structural and catalytic role during translation. rRNA builds the ribosome and acts as the enzyme (ribozyme).
(C) tRNA — this matches (I) amino acid carrier. tRNA brings amino acids to the ribosome.
(D) cistron — this matches (III) gene. A cistron is a segment of DNA coding for a polypeptide.
NCERT Extract:
Types of RNA and the Process of Transcription – “… In bacteria, there are three major types of RNAs: mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA). All three RNAs are needed to synthesise a protein in a cell. The mRNA provides the template, tRNA brings aminoacids and reads the genetic code, and rRNAs play structural and catalytic role during translation.”
