Open reading frame within a sequence that may be a gene, but has not yet been demonstrated as such.
Open reading frame. An open reading frame (ORF) is a portion of a gene's sequence that contains a sequence of bases, uninterrupted by stop sequences, that could potentially encode a protein. When a new gene is identified and its DNA sequence deciphered, it is still unclear what its corresponding protein sequence is. This is because, in the absence of any other knowledge, the DNA sequence can be translated or read in six possible reading frames (three for each strand, corresponding to three different start positions for the first codon). ORF identification involves scanning each of the six reading frames and determining which one(s) contains a stretch of DNA sequence bounded by a start and stop codon, yet containing no start or stop codons within it; a sequence meeting these conditions could correspond to the actual single product of the gene. The identification of an ORF provides the first evidence that a new sequence of DNA is part or all of a gene encoding for a particular protein.
Open Reading Frame; a reading frame refers to a nucleotide sequence that starts with an initiation codon, partitions the subsequent nucleotides into amino-acid-encoding triplets and ends with a termination codon. The interval between the start and stop codons is referred to as the open reading frame.
a series of nucleotide triplets (codons) coding for amino acids without any termination codons
Open reading frame. A series of DNA codons including a 5¡¯ initiation codon and a termination codon, that encodes a putative or known gene.
Open reading frame. The length of DNA sequence between the translation start signal and the termination codon that can be translated into a protein; the phase in which nucleotides can be read in sets of three that results in a protein.

open reading frame. a DNA sequence which is believed, on the basis of statistical evidence, to code for protein, but for which no matching protein or mRNA is known. ORFs can often be confirmed by matching their sequences to a database of known genes or EST's.
Open reading frame. A stretch of DNA which potentially codes for protein. A length of DNA not interrupted by stop codons. A sequence of in frame codons preceded by a translational initiation codon and terminated by a chain termination triplet.
Open reading frame. A continuous sequence of nucleotide triplets (codons) in which each triplet codes for an amino acid.
open reading frame; a stretch of DNA or RNA that contains of series of triplet codons coding for amino acids, without any protein termination codons, that is potentially translatable into protein. Return to text.
Open Reading Frame. Corresponds to a region of nucleotide sequence that may potentially be translated into a protein. This region usually begins with a "start" codon (nucleotide sequence 'ATG') and terminates with one of 3 "stop" codons. An ORF is not usually considered equivalent to a gene or locus until there has been shown to be a phenotype associated with a mutation in the ORF, and/ or an mRNA transcript or a gene product generated from the ORFs DNA has been detected.
(Open Reading Frame) A long DNA sequence that is uninterrupted by a stop codon and encodes mRNA that will intern be translated into part or all of a protein
Open reading frame. A stretch of DNA that when translated into an amino acid sequence doesnt contain an internal stop codon. An ORF can be evidence that a DNA sequence is part of a gene.
An ORF (Open Reading Frame) corresponds to a stretch of DNA that could potentially be translated into a polypeptide; i.e., it begins with an ATG "start" codon and terminates with one of the 3 "stop" codons. In dictyBase, currently all feature types are ORFs. There will be different features in the future.
open reading frame) A section of a sequenced piece of DNA that begins with a start codon and ends with a stop codon; it is presumed to be the coding sequence of a gene.
Open reading frame. contains a series of triplets coding for amino acids without any termination codons; sequence is (potentially) translatable into protein.
(open reading frame) A section of a sequenced piece of DNA that begins with an initiation (methionine ATG) codon and ends with a nonsense codon. ORFs all have the potential to encode a protein or polypeptide, however many may not actually do so.

Open reading frame. A series of DNA triplets that codes for amino acids without any stop signals and is potentially translatable into protein.
Open Reading Frame. A series of codons (base triplets) which can be translated into a protein. There are six potential reading frames of an unidentifed sequence; TBLASTN (see BLAST) transalates a nucleotide sequence in all six reading frames, into a protein, then attempts to align the results to sequeneces in a protein database, returning the results as a nucleotide sequence. The most likely reading frame can be identified using on-line software (e.g. ORF Finder).
