Biology notes about DNA's roll in a cell and how it is fitted in. Also includes plenty imformation on Chromosomes.

deoxyribonucleic acid directs a mobile ph adept and only(a)s activities and determines a prison cadres characteristic. This vast amount of vital training encoded in DNA is organized into genes. A gene is a discussion section of DNA that transmits information from p arent to offspring. When a cell prepares to divide, the DNA subatomic particle coils and twists into a dense structure called a chromosome. A chromosome is a rod- influenced structure that forms when a oneness DNA molecule and its associated proteins coil tightly before cell division. Chromosomes become indubitable through a microscope only later they have condensed forward to cell division. By this time, each chromosome has form a replicate of itself. The devil copies of each are called chromatids. The deuce chromatids are attach by a protein disk at a detail called a centromere. Human cells have 23 contrastive chromosomes. Your body cells (also called somatic cells) make up devil copies of each chromo some, for a total of 46 chromosomes. The dickens copies of each chromosome are called homologous chromosomes, or homologues. Homologous chromosomes are similar in general anatomy and size and have similar genetic information. You received one homologue of each chromosome from your mother and the other homologue from your father. When a cell contains two homologues of each chromosome, it is termed diploid. Not all cells are diploid. In the living bicycle of animals, including humans, gametes - eggs cells and sperm cells - are monoploid. A monoploid cell contains only one homologue of each chromosome. The fusion of two haploid gametes forms a diploid zygote.
A zygote is a fertilized egg cell, the first cell of a new individual. macrocosm haploid ensures that when an egg and a sperm fuse, the resulting zygote get out contain the characteristic diploid number of chromosomes for that organism. In just about cases, humans who are missing even one chromosome do...
