Aside from specific cells (as an example, semen and egg cells and red bloodstream cells), the mobile nucleus contains 23 pairs of chromosomes. A chromosome contains numerous genes. A gene is a segment of DNA providing you with the rule to make a protein.
The DNA molecule is an extended, coiled dual helix that resembles a spiral staircase. Inside it, two strands, composed of sugar (deoxyribose) and phosphate particles, are linked by pairs of four particles called bases, which form the actions associated with the staircase. Adenine is paired with thymine and guanine is paired with cytosine in the steps. Each couple of bases is held together with a hydrogen relationship. A gene is composed of a series of bases. Sequences of three bases rule for an acid that is amino acids will be the blocks of proteins) or other information.
