What is the function of messenger RNA (mRNA) in protein synthesis?

• To build the ribosome structure.

• To carry amino acids to the ribosome.

• To transcribe DNA into a message and deliver it to the ribosome.

• To act as an enzyme that speeds up protein formation.

What are proteins primarily composed of?

• DNA

• RNA

• Amino Acids

What is the function of tRNA during protein synthesis?

• To carry genetic instructions from the nucleus.

• To form the structural components of ribosomes.

• To deliver specific amino acids to the ribosome.

• To catalyze the formation of peptide bonds.

How does tRNA determine which amino acid to bring to the ribosome?

• It randomly selects an amino acid.

• It reads the sequence of three bases (codons) on the mRNA.

• It receives instructions directly from the DNA.

• It is guided by the ribosome's structure.

What is a codon?

• A single nucleotide base on mRNA.

• A sequence of three nucleotide bases on mRNA.

• A type of enzyme that builds proteins.

• The bond that links amino acids together.
