BIO 3170 Lecture Notes - Lecture 2: Intron, Functional Genomics, Karyotype
Document Summary
Bacteria only have one copy of the genetic material present, while humans have 46 copies. Dna lobes are part of the core protein in prokaryotic genomes, protein interacts directly with sugar molecules. There are proteins involved in the formation of the loops in dna. Most dna in prokaryote is for coding of proteins; Space between genes is very small; 0 to a few nts. Genes are organized into operons; 3 (for example) genes are clustered together, under control of same regulatory region. Sequence analysis: the change of how we draw phylogenetic traits; at the end of the trees, the ramifications are much more numerous (the bacteria are much more divided) Lateral movement: transmission of genetic material from one bacteria to another bacteria. Bacteria (blue oval) with plasmid will meet with another bacteria and connect, with the plasmid being copied in the new bacteria; the new bacteria may be integrated with plasmid.
