Unit 4 – Lecture 4. Mutations Genetic Mutation – a change in the amount or structure of genetic material of an organism Mutations can be in DNA or can.
Genes As Information. Alleles What alleles you have will determine what traits you have. Each person has two alleles, or versions, of each gene For example,
Moving materials in and out Transport within the cell Communication to and from nucleus Surface area to volume ratio decreases as a cell grows.

Cell Cycle. describes the life cycle of a cell differs fundamentally between prokaryotes & eukaryotes shares four features among all cell types –reproductive.
