Document Summary
All life is descended from a common ancestor, to the last universal common ancestor (luca) Homo sapiens: we are primates, mammals, vertebrate (backbone/spinal cord), chordate (have nerve cord but no spine), deuterostome (anus from blastopore, mouth from second opening), animals. Animals: motile (mobile) at some point of life, heterotrophs ("chemo") - oxidize organic molecules for energy. ex. Carbohydrates, sugars, fats: carbohydrate storage = glycogen, depend on other life forms for food, require oxygen to complete oxidization of molecules, eukaryotic, multicellular organisms. Human skin: comprised of epidermis and dermis layers. Human genome: types of dna: different sets of genes in each cell, but same dna. Mitochondrial genome: 46 chromosomes of linear double-stranded (ds) dna, 23 pairs chromosomes, 2 of each = 3,2000,000,000 base pairs, each mitochondrion contains. 1 chromosome (circular dsdna: = 16,569 nucleotide base pairs, muscle cells have a lot of these for energy.
