Reading frame

Reading frame
One of the three possible ways to read a nucleotide sequence in DNA (depending upon whether reading starts with the first, second or third base in a triplet).
* * *
The grouping of nucleotides by threes into codons. See frame-shift mutation.
- blocked r. a sequence of DNA that cannot be translated into a viable protein; usually due to the interruption by one or more termination codons. SYN: closed r..
- closed r. SYN: blocked r..
- open r. a gene presumed to code for a protein but for which no gene product has been identified; also known as unidentified r.. SYN: unidentified r..

one of the three possible ways of reading a nucleotide sequence as a series of triplets. An open reading frame contains no termination codons and is thus potentially translatable into protein.
