Overview of Genetic Variation at Molecular Levels

Clauddia Dodd


Genetics is the study of genes and genetic material in organisms. Genetic material is broad and expansive in humans, causing everyone to look so different from each other. There are various ways that genetic material can vary and many different mechanisms that are responsible for the differences. The list of these mechanisms is exhaustive, but here only the most important will be covered. To understand variance in human phenotypes, you must understand the structure of DNA, DNA folding, the Central Dogma, splicing, and mutations.
