Document Summary
Still changing as we understand more, dna is transcribed into rna and translated into proteins. Not always a bad thing, it can cause diversity in a species. Depends on where it happens, could affect a specific function in an organism, have to think about the consequences on the end product (protein) Can lead to changes in cellular function, how a pathway is regulated and structural components. Mutations can vary in size, could affect whole chromosome or a base pair. If you delete part of a chromosome, you delete a lot of information (dna is tightly packed) Somatic cell line vs germ cell line: somatic is mitosis and germ are reproduced through meiosis (gametes) Somatic cell mutations, we are not worried about it being passed onto the next generation (typically cancers without family history); non inheritable. In a germ line cell (egg and sperm), they can be inherited.
