Other than the two full sets of DNA, existent in every human body cell, there is an inherited genetic component, that is not contained in the cell nucleus, but resides in the mitochondria. Transcription is the process of reading a gene and extracting information from it, for protein synthesis. Here is a RNA/DNA codon translator, that will directly provide you with the amino acid associated with a particular nucleotide triplet combination.Ī gene is a segment of DNA, which is a series of codons that contains information about synthesis of a single or more proteins. More than one codon can translate into the same amino acid, which is a building block of proteins. The rest of three act as stop codons, that terminate the transcription process. To be precise, among the 64 codons, 61 encode amino acids (including the initiation codon in RNA, which is AUG). Each one of the codons encodes one of the 20 different amino acids. So the entire genetic code is written using just 64 different words. The four nucleotides form 64 (= 4 3) triplet combinations or codons. In RNA (Ribonucleic Acid) molecule, the genetic code is made up of the four letters, Adenine, Guanine, Cytosine, and Uracil (A, G, C, U). Adenine, Guanine, Cytosine, and Thymine (A, G, C, T) are the four nucleotides ( or letters) that form codons ( or words) in the DNA. It is entirely written with three-letter words, called codons. This book is unique, in the sense that it is written using just four alphabets, which are nucleotides. It is the recipe book, referred by cells, to produce proteins that make body functions possible.
This clearly proves the common origin of all life on our planet.ĭNA (Deoxyribonucleic Acid) is the molecule that contains all the genetic code of an organism. In essence, every single unicellular and multicellular life form, that has ever existed on Earth, has had a genome, made up of the same nucleotide subunits ( A, T/U, C, G). The basic building blocks of the genetic code are universal. Incontrovertible Evidence for the Unity of All Life
