Structure of mRNA and tRNA

Question 1

Structural similarities between mRNA and tRNA

Answer 1

• single polynucleotide chain
• pentose sugar, ribose and bases

Question 2

Structural differences between mRNA and tRNA

Answer 2

mRNA:
- longer
- single helix strand
- chemically unstable (only present for protein synthesis

tRNA:
- short chain
- amino acid attachment site on stalk and anticodon mRNA bind on lower lobe
- Chemically stable
