* DNA's Code: DNA contains the genetic instructions for building and maintaining an organism. These instructions are encoded in the sequence of its four nitrogenous bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
* Transcription: The first step is transcription, where a copy of the DNA sequence is made in the form of messenger RNA (mRNA). This copy uses the same nitrogenous bases as DNA, except thymine is replaced with uracil (U).
* Translation: The mRNA then travels out of the nucleus to the ribosomes, where translation occurs. Here, the mRNA sequence is read in groups of three bases called codons. Each codon codes for a specific amino acid.
* Amino Acids: The ribosome assembles the amino acids in the order dictated by the mRNA codons, forming a chain. This chain folds into a specific three-dimensional shape, creating a functional protein.
In short, DNA's nitrogenous bases hold the blueprint for protein production. This blueprint is transcribed into mRNA, which is then translated into a chain of amino acids that fold into a functional protein.
