Reading Frame Definition Biology. In genes that lack introns (e.g. Web overview reading frame quick reference a sequence of bases in messenger rna (or deduced from dna) that encodes for a polypeptide.

Since each coding unit ( codon ) of the genetic code consists of three consecutive bases, the reading frame is established according to precisely where translation starts. Most prokaryotic genes), an orf in the dna sequence will define the entire translated region. In molecular biology, open reading frames ( orfs) are defined as spans of dna sequence between the start and stop codons. Web reading frame a sequence of bases in messenger rna (or deduced from dna) that encodes for a polypeptide. In genes that lack introns (e.g. Web overview reading frame quick reference a sequence of bases in messenger rna (or deduced from dna) that encodes for a polypeptide. We can start translating, or reading, the dna from the first letter, 'a,' which would be referred to as the first reading frame. Web open reading frame sample sequence showing three different possible reading frames. A reading frame refers to one of three possible ways of reading a nucleotide sequence. Web an open reading frame (orf) is a series of codons that begins with a start codon (usually aug) and ends with a stop codon.
Web reading frame determines how the mrna sequence is divided up into codons during translation. As the genetic code is read in nonoverlapping triplets (codons) there are three possible ways of translating a sequence of nucleotides into a protein, each with a different starting point. Most prokaryotic genes), an orf in the dna sequence will define the entire translated region. In genes that lack introns (e.g. The mrna below can encode three totally different proteins, depending on the frame in which it's read: What it refers to is a frame of reference, and what is being read, reading, is the rna code, and it is being read by the ribosomes in order to make a protein. Web reading frame a sequence of bases in messenger rna (or deduced from dna) that encodes for a polypeptide. Let's say we have a stretch of 15 dna base pairs: Web the meaning of reading frame is a sequence of nucleotide triplets that is potentially translatable into a polypeptide and that is determined by the placement of a codon that initiates translation. One of the three possible ways of reading a nucleotide sequence. Start codons are highlighted in purple, and stop codons are highlighted in red.
