The correct answer is Option (3)- 1-b,2-c,3-d,4-a
| Column 1 |
Column 2 |
| 1) mRNA |
b) Provides the template |
| 2) tRNA |
c) Brings amino acids and reads the genetic code |
| 3) rRNA |
d) Structural and catalytic role during translation |
| 4) Introns |
a) Don't appear in mature RNA |
mRNA - b) Provides the template
- Explanation: Messenger RNA (mRNA) carries the genetic information from DNA to the ribosome, where it serves as a template for protein synthesis during translation.
tRNA - c) Brings amino acids and reads the genetic code
- Explanation: tRNA has an anticodon loop that has bases complementary to the code, and it also has an amino acid acceptor end to which it binds to amino acids. tRNAs are specific for each amino acid. tRNA brings amino acids and reads the genetic code.
rRNA - d) Structural and catalytic role during translation
- Explanation: Ribosomal RNA (rRNA) is a key structural component of ribosomes and also has a catalytic role in protein synthesis, specifically in the formation of peptide bonds between amino acids.
Introns - a) Don't appear in mature RNA
- Explanation: Introns are non-coding sequences in a gene that are transcribed into RNA but are removed during RNA processing. They do not appear in the mature mRNA, which is used for translation. Primary transcripts contain both the exons and the introns and are non-functional. Hence, it is subjected to a process called splicing where the introns are removed and exons are joined in a defined order.
