Definitions:

Ribosomal Subunit

A structural component of ribosomes, which comes in two sizes (large and small), necessary for protein synthesis in cells.

Prokaryotic Translation

The process by which mRNA is decoded by a ribosome to produce a specific protein in prokaryotes, organisms without a nucleus.

Initiation Complex

A complex of proteins and RNA that forms on mRNA to begin the process of translating RNA into a polypeptide chain in the cell.

Nonsense Mutation

A base-pair substitution mutation that results in an amino acid–specifying codon being changed to a termination (stop) codon; when the abnormal mRNA is translated, the resulting protein is usually shortened and nonfunctional. Compare with missense mutation.
