What is the major difference between mRNA and tRNA?

• Only tRNA has thymine.

• Only mRNA has uracil.

• Only mRNA has ribose as its sugar.

• Only tRNA is shaped like a three- leafed clover

The "central dogma" states that genetic information flows from 

• Protein-->mRNA-->DNA

• Protein-->DNA-->mRNA

• mRNA-->DNA-->Protein

• DNA-->mRNA-->Protein
