Document Summary

The genetic material must store genetic information and accurately transmit that information from parents to offspring , generation after generation: the phenotypic function, gene expression. The genetic material must control the development of the phenotype of the organism. That is, the genetic material must dictate the growth of the organism from the single-celled zygote to the mature adult: the evolutionary function, mutation. The genetic material undergo changes to produce variations that allow organisms to adapt to modifications in the environment so that evolution can occur. In most organisms, the genetic information is encoded in dna. Chromosomes are composed of two types of large organic molecules called proteins and nucleic acids. The nucleic acids are two types: deoxyribonucleic acid (dna) and ribonucleic acid (rna) The genetic material must perform 3 essential functions: the genotypic function (replication), the phenotypic function (gene expression), and evolutionary function (mutation) the genetic material.
