ANTH 101 Lecture Notes - Lecture 4: Transfer Rna, Ribosome, Population Genetics
Document Summary
Dna: found in every living organism, contains instructions for making every cell in the human body, double helix (ladder) Legs made up of phosphates and sugars. Mrna makes copies of dna contained within cell: ribosome. Mrna leaves cell connects to ribosome: translation. Ribosome uses trna (transfer rna) to read codons: codon: set of 3 base pairs. Ribosome produces one amino acid per codon. Thursday, september 10, 2015: build up and held together by a peptide bond, protein synthesis. Amino acids build up and form a polypeptide chain. Proteins lead to phenotypes (physical formation of genes in dna) Genes: portion of dna read by rna results in the formation of different proteins, fundmental heritable unit responsible for the formation of an organism, structural. Turn other genes on and off: homeotic genes (hox genes) Responsible for how organism forms, and arrangement of organs. Turn on and off at different times and different locations to form different parts of an organism.
