Document Summary
Each cell in the human body has 46 chromosomes (23 pairs) Chromosomes are filled with dna = genetic blueprint. Dna is comprised of four nucleotide bases: all of our genetic material is encompassed in sequences of those bases. It"s through dna replication during mitosis that we understand why every cell in an organism contains exactly the same genetic material. Genotype the genetic material an individual inherits. Phenotype the observable expression of the genotype including both body characteristics and behavior. Specific segment of dna, responsible for the production of a specific proteins. Every individual has two copies of each gene, one on the chromosome inherited from the father and one on the chromosome inherited form the mother. The human genome project was developed to determine the sequence of these 3 million nucleotide pairs on the 46 chromosomes. There are about 21,000 genes in the human body.
