Question

Differentiate between m-RNA, t-RNA and r-RNA.

Answer 1

Sr. No.	m-RNA	t-RNA	r-RNA
1.	m-RNA is a simple molecule with a linear structure and no folds.	t-RNA is a molecule with a single strand. This molecule has a consistent folding pattern.	rRNA is a single-stranded RNA that folds on itself in diverse ways. It exhibits complimentary base pairing in the folded regions.
2.	It transports the message from DNA to ribosomes, indicating which sort of protein to be made.	It is responsible for transporting amino acids during translation.	This RNA is permanently linked to the ribosomes. It provides an m-RNA binding site.
3.	3–5% of total cellular RNA is m-RNA.	t-RNAforms account for around 10-20% of total cellular RNA.	In terms of total cellular RNA. rRNA accounts for 80% of the total.
4.	It has a molecular weight of around 500,000 daltons.	t-RNA is the smallest RNA, containing just 73-93 nucleotides and weighing between 23,000 and 30,000 daltons.	The molecular weight of r-RNA ranges between 40,000 and 10,000 daltons.
