WebHaploid human genomes, which are contained in germ cells (the egg and sperm gamete cells created in the meiosis phase of sexual reproduction before fertilization) consist of 3,054,815,472 DNA base pairs (if X chromosome is used), [3] while female diploid genomes (found in somatic cells) have twice the DNA content. WebEach nucleotide in DNA contains one of four possible nitrogenous bases: adenine (A), guanine (G) cytosine (C), and thymine (T). Adenine and guanine are purines, meaning that their structures contain two fused carbon-nitrogen rings. Cytosine and thymine, in contrast, are pyrimidines and have a single carbon-nitrogen ring.

WebEach DNA sequence containing protein instructions is known as the gene. The gene size can vary considerably, from about 1000 bases to 1 million bases in humans. Genes represent only 1% of the DNA sequence. DNA sequences outside of these 1% are involved in regulation when, like, how many proteins are produced. What's the DNA doing?
