Does Dna Change Over Generations at Adela Spooner blog

Does Dna Change Over Generations. This is the process of epigenetics, where the readability, or expression, of genes is modified without changing the dna code itself. As such, the nucleotide sequences found within it are subject to change as the result of a phenomenon called mutation. Tiny chemical tags are added. Dna methylation is one of the most common epigenetic tags. Virtually the first thing a young population genetics student will learn is that changes in gene frequency can be caused by genetic drift, natural selection, and migration. Analyses of thousands of sequenced genomes show changes in as little as a generation. When particular genetic sequences change in a population (e.g., via mutation) and these changes are inherited across successive generations, this is the stuff of evolution. Humans are still evolving—and we can watch it happen. Dna is a dynamic and adaptable molecule. It involves the addition of a methyl group (one carbon atom and three hydrogen atoms) to the dna’s surface.
