WebOne of three possible reading frames in which an mRNA is potentially translated into protein. In analysis of a DNA sequence, an ORF is characterized by the sequence of nucleotides that when transcribed into mRNA results in a series of triplet codon s that is not interrupted by a translation termination codon.

WebTranscription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages: initiation, elongation, and termination. o mere shyamWebreading frame. The sequence of nucleotide triplets (codons) that runs from a specific translation start codon in a mRNA to a stop codon. Some mRNAs can be translated into different polypeptide s by reading in two different reading frame s.
