Document Summary
Evolution = change in gene frequency in population over time. Studying genetics: process of inheritance, molecular level, population level. Discovery of dna molecule: in 1869 miescher isolated dna molecule, unsure if it contained genetic information, watson & crick discovered structure of dna. Both worked at cavendish lab at cambridge which was competing with. Randall lab at cambridge to discover structure of dna: rosalind franklin realized dna was a double helix and her images were secretly shown to watson & crick. They then came up with the hypothesis for the structure of dna based on that information. Gene = basic unit of inheritance: 2 types of genes structural genes code to produce body structures and specific products regulatory genes. First human genome was published in 2003, took 10 years to sequence and. Now can be done in about a week and costs . Genomes of more than 180 different species has been sequenced: functions of dna.
