an ORF is the part of the mRNA sequence, starting at an intiation codon (usually AUG), that terminates either at a stop codon (TAA, TAG or TGA for the standard genetic code), or at the end of the sequence, if no stop codon is found in the same phase; the later case meaning that the mRNA sequence is incomplete. Author summary Translation is an essential step in which ribosomes decipher mRNA sequences to manufacture proteins. Recent advances in time-lapse fluorescence microscopy allow live-cell quantification of translation dynamics at the resolution of single mRNA molecules. Here, we develop a flexible computational framework to reproduce and interpret such experiments. We use this framework to ... Nov 15, 2013 · This video shows how to decode the DNA code. We convert the DNA message into the sequence of mRNA bases, then convert to tRNA bases and finally we show the amino acids. The answer: by means of transfer RNA molecules, each specific for one amino acid and for a particular triplet of nucleotides in messenger RNA (mRNA) called a codon. The family of tRNA molecules enables the codons in a mRNA molecule to be translated into the sequence of amino acids in the protein. a) A codon is a sequence of three bases that indicates a unit of information in the RNA. A gene is a series of codons that results in the production of a protein. Identify the codons of the mRNA shown. The start codon for a gene is AUG, so start by dragging the blue start codon box over the AUG on the strand.
