Protein Synthesis

What is the main function of DNA?

• Store genetic information

• Carry amino acids

• Build ribosomes

• Produce energy

Which base is found in RNA but not DNA?

• Adenine

• Guanine

• Uracil

• Thymine

Where does transcription occur in eukaryotic cells?

• Cytoplasm

• Ribosome

• Nucleus

• Mitochondria

What is the role of mRNA?

• Delivers amino acids to the ribosome

• Acts as a template for protein building

• Forms part of the ribosome structure

• Stores genetic instructions permanently

The building blocks of proteins are:

• Nucleotides

• Amino acids

• Ribosomes

• Codons
