Answer 1

mRNA — messenger RNA; a single-stranded RNA copy of a gene that carries the genetic code from DNA in the nucleus to the ribosome for protein synthesis.

deoxyribose — the five‑carbon sugar in DNA that lacks an oxygen atom on the 2' carbon (compared to ribose).

nitrogenous base — a nitrogen-containing molecule that is part of a nucleotide (A, T, C, G in DNA; A, U, C, G in RNA).

nucleotide — the monomer of nucleic acids, consisting of a phosphate group, a five‑carbon sugar, and a nitrogenous base.

rRNA — ribosomal RNA; the RNA component of ribosomes that provides structure and catalyzes peptide bond formation during translation.

amino acids — the small organic molecules that are the building blocks of proteins; each is specified by one or more mRNA codons.

codon — a sequence of three nucleotides on mRNA that specifies a particular amino acid or a stop signal during translation.

ribose — the five‑carbon sugar present in RNA that has a hydroxyl group on the 2' carbon.

transcription — the process of synthesizing an RNA molecule (usually mRNA) from a DNA template.

translation — the process by which ribosomes read mRNA codons and assemble the corresponding amino acids into a polypeptide (protein).
