Example sentencesExamples
- Proteins encoded in overlapping reading frames from the same nucleotides have different levels of amino acid variation.
- The open reading frames of all gene sequences identified were interrupted by introns.
- The alignment exhibited an insertion of 11 consecutive codons after the first 2 codons in the reading frame of the S gene.
- The leader transcript contains an open reading frame which encodes a polypeptide of 44 amino acids.
- Analysis of the nucleotide sequence identifies an open reading frame of 1882 codons, interrupted by one putative intron.
