Document Summary
30 techniques to study genes 31 applications of. Lecture 1: introduction to cells, genes and diversity. Life originated on earth approximately 4 billion years ago. Evolve and are adapted to their environment. 96% of living matter consists of carbon, oxygen, nitrogen, hydrogen. Polarity results in hydrogen bonding (h slight positive charge) Include fats (storage), phospholipids (membranes) and steroids. Phospholipids hydrophilic head & 2 hydrophobic tails (diagram). Account for 50% of dry cell weight. Many functions: structure & support, storage, transport, hormonal, receptors, contradiction, defence, enzymatic degradation (digestions). >one base different uracil instead of thyamine. >usually single stranded instead of double stranded as in dna. Carries amino acids to ribosome and recognizes the codon on mrna. Lectures 4 & 5: the diversity and structure of prokaryotes. Lecture 4 & 5 notes: all living things are composed of cells, cells are different shapes, sizes and have different functions, two types of cells: prokaryotes and eukaryotes.
