What determines the sequence of amino acids in a protein?
DNA and genes
The sequence of amino acids in a protein is determined by the genetic code or the DNA sequence. The DNA sequence contains genetic information that encodes the sequence of amino acids in a protein. Three consecutive nucleotides in the DNA sequence correspond to one amino acid in a protein. This triplet nucleotide sequence is called a codon, which codes for a particular amino acid.
During protein synthesis, ribosomes read the codons in the mRNA sequence and assemble the corresponding amino acids in the correct order to form a polypeptide chain that folds into a functional protein. There are 20 different types of amino acids that make up proteins, and the order in which they are assembled determines the structure and function of the protein. Small changes in the DNA sequence can alter the amino acid sequence of a protein, which can affect its function and cause genetic diseases.
Therefore, the sequence of amino acids in a protein is determined by the DNA sequence, which dictates the order of codons that correspond to the specific amino acids that will be incorporated into the protein.
