Reading frame biology definition
In molecular biology, a reading frame is a way of dividing the sequence of nucleotides in a nucleic acid (DNA or RNA) molecule into a set of consecutive, non-overlapping triplets. Where these triplets equate to amino acids or stop signals during translation, they are called codons. A single strand of a nucleic acid molecule has a phosphoryl end, called the 5′-end, … WebMar 1, 2024 · Keywords. Open reading frame (ORF) is a basic term in molecular genetics and bioinformatics. The detection of ORFs is an important step in finding protein-coding genes in genomic sequences, including analyses based on highly fragmented draft (meta)genome assemblies 1, 2, 3. ORFs can be detected by simple in silico analysis, while …

Most importantly, the position of the start codon determines the reading frame, or how the mRNA ... WebAn Open Reading Frame (ORF) is considered the region of a nucleotide that begins with an initiation codon and ends with a stop codon. The triplet codon that codes for the first amino acid in the translation process is an initiation codon. Only the initiation codon, ATG, which codes for the amino acid methionine, will begin the translation process.
