Document Summary
Lecture 4: bioinformatics: develops and improves on methods for storing, organizing, retrieving, and analyzing biological data. Has been mostly about computer science rather than biology. Objective of bioinformatics: to generate knowledge about biological processes. Not a necessity but most hot research areas involve genetic data. Also includes protein-protein interactions, evolutionary biology, systems biology, etc. Traits (e. g. , eye colour, height) are inherited from ancestors. Proteins carry out various functions at the cellular level. Same copies are stored in every cell of an organism. Dna (deoxyribonucleic acid): molecule that encodes genetic information, every living organism has it in every cell, double-helix structure, basic unit is nucleotide. Consists of a nucleobase and a backbone: 4 nucleobase types: A stretch of dna related to a specific function or a trait. Genome: complete set of an organism"s genetic information. mitochondria. Humans carry dna sequences in cell nuclei and a small dna molecule in. Only 2% of human genome is protein coding.
