II. Double-stranded DNA serves as a genetic blueprint.
III. Messenger RNA travels to the ribosome.
IV. Proteins are produced by the ribosome in translation.
V. Transcription creates a messenger RNA copy of a gene in the DNA.

the answer is d p: cell, q: organ, r: organ system, s: tissue

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.
