What process is shown in the diagram?

• replication
• transcription
• mitosis
• translation

The main function of tRNA is to...

• carry a message that, when translated, forms proteins
• form a portion of ribosomes
• string together complementary RNA and DNA strands
• bring amino acids from the cytoplasm to the ribosomes

The "blueprint" is found in the nucleus of each cell in the form of DNA.

• True

• False

What occurs during protein synthesis?

• Nitrogen bases create sugar molecules.

• Amino acids link together to form proteins.

• Protein molecules create new music.
