Document Summary

Dna makes more copies of itself through division. Genetic material has 3 functions genotypic function (replication), phenotypic function (gene expression, and evolutionary function (mutation) How instructions are interpreted determine the phenotype. Replication in two ways mitotic division. Quality of a genome judged by if it can pass on necessary genes for life. Even though we have specific instructions, the genome is not the determinant, the genome works with the environment. Picture has same dna sequences but look very different from each other (left is harder for predators to eat) Evolution has to do with mutation, mistakes sometimes happen when division occurs (changes in the dna sequence, can be advantageous, detrimental or cause no change) Variation in lady bugs is caused by mutations. Dna (deoxyribonucleic acid) is an acid, a polymer that is made up of individual subunits called nucleotides which in turn are made up of three parts (phosphate group, five carbon sugar, and one of four cyclic nitrogenous bases)
