The relationship between nucleotide sequence and amino acid sequence is called the genetic code.

In those segments of DNA that carry information about proteins, the sequence of the nucleotides determines the sequence of amino acids in a polypeptide chain (one chain of a protein).
A group of three consecutive nucleotides codes for (represents) one amino acid. This group is called a codon.
The different amino acids are coded for by different codons. What each of the 64 codons stands for is the genetic code.
Three of the codons mean STOP; each of the 61 others stands for one of the 20 amino acids. In addition, one of the codons does double duty: it means START when it appears in a particular position.
The coding sections of DNA are called genes. Some genes code for RNA (such as transfer and ribosomal RNA); polypeptide chains are coded for by other genes, or, more specifically, exons of those genes. The exons are often separated by introns, which, although consisting of a sequence of nucleotides, do not code for amino acids.
The idea that nucleotide sequence (often referred to as base sequence) might code for amino acid sequence followed the proposal of the double-helix structure for DNA in 1953.
In 1958 Francis Crick gave the name sequence hypothesisto the idea that the nucleotide sequence corresponded to the sequence of amino acids in the chain to be synthesized. (For some reason this name is not well known now, and is often confused with Crick's term "central dogma", which, as Crick used it, denotes a different concept.)
In 1961 there were two important breakthroughs. Crick and Sydney Brenner showed that the code consisted of "triplets" (Brenner coined the word codon the following year), and Marshall Nirenberg and Heinrich Matthaei developed a technique for working out the code (in its messenger RNA version).
By 1966 all the 64 possible codons had been worked out.
A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid during protein synthesis. Each codon codes for a particular amino acid, which is determined by the genetic code. The relationship between an amino acid and a codon is that the genetic code dictates which codons correspond to each amino acid, ensuring the correct sequence of amino acids in a protein.
The codon AUG represents the amino acid methionine, which serves as the start codon for protein synthesis. The codon GUG typically codes for the amino acid valine.
amino acid
Codon.
The amino acid "ucg" does not exist in the standard genetic code and is not recognized as a valid codon. It is not associated with any specific amino acid.
The start codon is AUG, which codes for the amino acid methionine in most eukaryotic cells. Methionine also serves as the initiator amino acid for protein synthesis.
No, tryptophan is an amino acid and not a starting codon for mRNA. The starting codon for mRNA is typically AUG, which codes for the amino acid methionine in most cases.
The DNA codon TAC codes for the amino acid Tyrosine.
A codon contains three amino acids. Each codon in mRNA corresponds to a specific amino acid in a protein sequence.
The codon AUG represents the amino acid methionine, which serves as the start codon for protein synthesis. The codon GUG typically codes for the amino acid valine.
The codon AUC codes for the amino acid isoleucine.
It is CAC and CAU.
One codon specifies a specific amino acid. However, more than one codon can code for the same amino acid. For example, the codon GUU codes for the specific amino acid valine; and the codons GUC, GUA, and GUG also code for valine.
The mRNA codons for histidine are CAU and CAC.
a codon is the sequence of three nucleotides of mRNA, the anti codon is the amino acid of tRNA that is matched to the codon.
amino acid
The term is "codon." Each codon corresponds to a specific amino acid or serves as a start or stop signal for protein synthesis.
There is only one corresponding amino acid for each codon. Each codon codes specifically for one amino acid (however, an amino acid can be coded for by several different codons). For example: CAU codes for Histamine (and not any other amino acid) But, CAC also codes for Histamine.
