ANTA01H3 Chapter Notes - Chapter 3: Genetic Drift, Mitosis, Meiosis
Document Summary
Genetics: study of gene structures and action and the pattern of transmission of traits from parent to offspring. Genetic mechanisms are the foundation for evolutionary change. Nucleus: organelle found in all eukaryotic cells - contains dna. 3 diff single stranded forms of rna are essential to protein synthesis. Cytoplasm: portion of cell contained within cell membrane (not including nucleus) consists of a semi-fluid material and contains. Proteins: 3d molecules that serve a wide variety of functions through their ability to bind to other molecules. Somatic cells: all the cells in the body except those involved with reproduction. Gametes: reproductive cells (egg and sperm in animals) developed from precursor cells in ovaries and testes. Zygote: cell formed by union of egg and sperm. Contains full complement of chromosomes (46 in humans) and has potential to develop into an entire organism. Molecule: structure made of 2 or more atoms. Can combine with other molecules to from complex structures.
