Here's what I've understood: mutations occur when there is a change in the sequence of the genetic code. If non-disjunction occurs during cell division, leaving cells with too few or too many copies of a given chromosome, the code has not actually been altered. What has changed is the number of copies of specific parts of its genetic code.The liver, a unique organ with regenerative abilities, plays a crucial role in metabolism, nutrient storage, and detoxification. It breaks down nutrients (catabolism) and builds larger macromolecules (anabolism). It stores carbohydrates and fats as glycogen, lipoproteins, and triglycerides.
