Molecular genetics is the study how genes change overtime and the structure and function of genes at the molecular level. Evolutionary biologists had to make inferences based off of phenotypic observations before molecular genetics was established. We can use molecular genetics to prove evolution by how our genes and traits do change overtime due to diseases inherited from our parents, the environment we live in, both the actual living environment and the nutritional standpoint, and the lifestyle habits can affect our genes, which alter the future of evolutionary change. Darwin’s definition of theory is stated as the change in the genetic structure of population, frequently used to refer to the appearance of new species. Changes allow the organisms to better adapt to the environment, which in turn will help them survive and produce more offspring. Understanding DNA can take a lot of studying and confusion to even get the general idea of the concept. The structure of DNA is very complicated and complex to understand, but researchers James Watson, Francis Crick, Maurice Wilkins, and Rosalind Franklin all developed the idea of the DNA structure in 1953. Deoxyribonucleic Acid is found in the nucleus of the cell. It is a double stranded molecule that contains the genetic code and is the main component of chromosomes. DNA is the blueprint of organisms. Nucleotides are the basic unit of DNA and they are made up of sugar, phosphate, and one of the four basis including adenine,
