ANT101H5 Chapter 3: Chapter #3 (Heredity and Evolution)
Document Summary
Chapter #3 heredity and evolution: the study of gene structure and action and the pattern of transmission of traits from parent to offspring, genetic mechanisms are the foundation for evolutionary change. The basic units in all living things: there are multicellular organisms and single-cell organisms (such as bacteria) Prokaryotic cells: single-celled organisms represented today by bacteria and blue-green algae. Eukaryotic cells: structurally more complex, found in all multicellular organisms, the focus of the following notes unless stated otherwise. Nucleus: a structure (organelle) found in all eukaryotic cells, contains chromosomes (nuclear dna) Deoxyribonucleic acid (dna: the double-stranded molecule that contains the genetic code, the main component of chromosomes. Ribonucleic acid (rna: a molecule similar in structure to dna, three different single-stranded forms of rna are essential to protein synthesis. Proteins: three-dimensional molecules that serve a wide variety of functions through their ability to bind to other molecules.
