Document Summary
Bioinformatics = computational methods for studying large data sets. Linkage map physical map overlapping segment sequencing: crossover frequencies and assign each of the genes to a chromosome then cut the chromosome, sequence went into a public database. Systems biology: opposite of reductionism (looking at a small part of something and trying to understand it) Looking at a large part of something and trying to understand it: do in one organism or cell but you can also do it between cells. Genome sizes bacteria 1- 6 million bases: no introns, not a lot of noncoding sections, some introns is archaea plants and animals > 100 million bases humans 3200 million bases mammals have the lowest gene density. Just because it has more genomes does not mean it is higher on the evolutionary chain transposable elements. Alu elements super long sequences (thousands or millions of nucleotides) short sequences (2 to 5 nucleotides) Alu elements (primates) = a type of transposable element.
