Julio Hernandez Genetic Mutation is a change of the nucleotide sequence of a genome. Mutations result from un-repaired damage to DNA or RNA genomes usually caused by radiation or chemical mutagens or from errors in the process of replications. Mutations play a part in both normal and abnormal biological processes‚ including evolution‚ development of the immune system‚ and cancer. There are two main types of genes that play a role in cancer‚ ocnogenes and tumor suppressor genes. An important

In humans‚ biological aging falls under two categories of theories: the programmed aging and the damage theories. Programmed aging theories include the programming of genes‚ hormones and the immune system to regulate aging‚ while the damage theories concern free radicals and wear and tear (Jin‚ 2010). Damage to molecules‚ cells and organs always accompany aging‚ resulting in age-related diseases.
