How a gene codes for a polypeptide
WebMost codons specify an amino acid. Three "stop" codons mark the end of a protein. One "start" codon, AUG, marks the beginning of a protein and also encodes the amino acid methionine. Codons in an mRNA are read … Web17 de mai. de 2024 · This code either matches an amino acid or tells the cell when it is time to start (start codon) or stop (stop codon) adding amino acids to a polypeptide chain. All codons are made up of three nucleotide bases and named according to the order of these bases – for example, the stop codon TAG tells us that it is made up of thymine, followed …

WebA gene is a section of DNA used to produce a single polypeptide, or protein molecule, which is made of amino acids. The process of protein synthesis can be divided into two parts. The first part is transcription, which produces a molecule of messenger RNA (mRNA) from the gene. Transcription takes place in the nucleus of the cell. Web9 de mar. de 2024 · One of the definitions of a gene is as follows: a segment of deoxyribonucleic acid (DNA) carrying the code for a specific polypeptide. Each …
WebGenetic code is a set of codons present in the mRNA (messenger ribonucleic acid). Each codon codes for a specific amino acid. A set of three nitrogen bases forms one codon and decodes amino acids. Thus, if polypeptide comprises a total of 51 amino acids. The number of nitrogen bases in the gen or mRNA is 51 multiplied by three, which equals 153.
