WebReading frame. In biology, a reading frame is a contiguous and non-overlapping set of three- nucleotide codons in DNA or RNA. There are 3 possible reading frames in a mRNA strand and six in a double stranded DNA molecule due to the two strands from which transcription is possible. This leads to the possibility of overlapping genes and there may ... WebA codon is a set of three nucleotides, a triplet that code for a certain amino acid.The first codon establishes the reading frame, whereby a new codon begins. A protein's amino acid backbone sequence is defined by …

In molecular biology, a reading frame is a way of dividing the sequence of nucleotides in a nucleic acid (DNA or RNA) molecule into a set of consecutive, non-overlapping triplets. Where these triplets equate to amino acids or stop signals during translation, they are called codons. A single strand of a nucleic acid molecule has a phosphoryl end, called the 5′-end, … WebMar 2, 2024 · Overlapping genes (OLGs) or dual-coding genes utilize two different reading frames or initiation codons for encoding more than one protein.
