Document Summary
Systematic study at the molecular level of entire genome, and its products. Description of how genome contributes to unfolding of the cell, organism, population, ecosystem. Molecular biology and genetics on a large scale: encompass larger: what is a genome? and more complex data sets. Some paragraphs easier to understand than others. Organizes complex interactions in space and time. Less than 2% are coding for proteins: gene numbers, density and genome size. Loose correlations between: genome size and organismal complexity, genome size and number of genes, genome size and gene density (inverse correlation, viruses and their genomes. Have two main phases: dispersal via virions (particles, reproduction in human cells. Genomes: minimum set of genes required to infect. Use computers to look for certain common gene motifs (promoters (tataa box), sequences that code for protein (exons), intron recognition sequences, polya. Sequence mrna, then look for the same sequences in the dna.
