With the exception of specific cells (as an example, semen and egg cells and red bloodstream cells), the cellular nucleus contains 23 pairs of chromosomes. A chromosome contains genes that are many. A gene is a part of DNA providing you with the rule to make a protein.
The DNA molecule is a lengthy, coiled double helix that resembles a staircase that is spiral. Inside it, two strands, consists of sugar (deoxyribose) and phosphate particles, are linked by pairs of four molecules called bases, which form the actions associated with staircase. When you look at the steps, adenine is combined with thymine and guanine is combined with cytosine. Each set of bases is held together by way of a hydrogen relationship. A gene is made of a series of bases. Sequences of three bases rule for an amino acid (amino acids are the blocks of proteins) or any other information.
A collection of normal chromosomes from a male. The sex chromosomes (final set) are designated XY.
