Question

What is the primary function of tRNA in protein synthesis? (1 point)
• Carrying genetic information from DNA to the ribosome
• Binding to amino acids and delivering them to the ribosome.
• Forming peptide bonds between amino acids.
• Unwinding the DNA double helix.

How does the sugar in RNA differ from the sugar in DNA? (1 point)
• RNA contains fructose, while DNA contains glucose
• RNA contains glucose, while DNA contains fructose
• RNA contains ribose, while DNA contains deoxyribose
• RNA contains deoxyribose, while DNA contains ribose

Answer 1

1) Binding to amino acids and delivering them to the ribosome.
- tRNA carries specific amino acids and matches them to codons on mRNA at the ribosome.

2) RNA contains ribose, while DNA contains deoxyribose.
- RNA has a hydroxyl on the 2' carbon (ribose); DNA lacks that OH (deoxyribose).
