Question:
The most abundant type of RNA in a metabolically active mammalian cell is
The most abundant type of RNA in a metabolically active mammalian cell is
Updated On: Jan 9, 2025
- mRNA
- rRNA
- snoRNA
- tRNA
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Ribosomal RNA (rRNA) constitutes about 80% of the total RNA in a cell. It is a key component of ribosomes, where protein synthesis occurs. In contrast, messenger RNA (mRNA) and transfer RNA (tRNA) make up smaller proportions and serve as intermediaries in protein synthesis.
