The upcoming discussion will update you about the comparison of different types of RNA.

m – RNA:

1. Percentage of Cell is 5%

2. Molecular Weight is 5,00,000

3. Origin from DNA of Chromosome

4. Nucleotides are 900-1200

5. Sedimentation coefficient is 8S

6. Structure containing the triplet codons

7. Synthesis in eukaryotes by RNA pol II

8. Function is to Carry codons for polypeptide synthesis

t – RNA:
