Reading frame biology definition
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. WebCodons. Cells decode mRNAs by reading their nucleotides in groups of three, called codons. Here are some features of codons: Most codons specify an amino acid. Three "stop" codons mark the end of a protein. One …
