The protein-coding region(s) of each mRNA is composed of a contiguous, non-overlapping string of codons called an open reading frame (commonly known as an ORF).

Translation starts at the 5’end of the ORF and proceeds one codon at a time to the 3’end. The first and last codons of an ORF are known as the start and stop codons.

mRNAs containing multiple ORFs are known as polycistronic mRNAs, and those encoding a single ORF are known as monocistronic mRNAs.
