3230:150 Lecture Notes - Lecture 2: Nuclear Dna, Nuclear Membrane, Dna Replication
Document Summary
Chapter 3 genetics reproducing life and producing variation. Two types of organisms prokaryote- single celled organisms, its dna is not in a membrane-bound nucleus. No nuclear membrane eukaryote- multi-celled organisms, its dna is contained in a membrane-bound nucleus. An organism whose cells have nuclei somatic cells- cells that form most parts of an organism"s body. Can only go through a max of 43 divisions, it will then die gametes- sex cells (sperm, eggs, pollen, ovules) Dna molecule nuclear dna- contained within the nucleus of a cell. A single human liver call has between 1000-2000 mitochondria. On each side of the ladder, every unit of sugar, phosphate, and nitrogen base from a single nucleotide. The base can be adenine (a), thymine (t), guanine (g), or cytosine (c) Part of a cell division is meiosis and mitosis. Dna makes identical copies of itself chromosome types- occur in homologous pairs (matching)
