Which of the following is not a property of open reading frame?

WebOne common use of open reading frames (ORFs) is as one piece of evidence to assist in gene prediction. Long ORFs are often used, along with other evidence, to initially identify … WebAn open reading frame (ORF) is a series of codons that begins with a start codon (usually AUG) and ends with a stop codon. There can be no additional stop codons within that sequence. In genes that lack introns (e.g. most prokaryotic genes), an ORF in the DNA sequence will define the entire translated region. the queens head crowmarsh gifford
