Whole Genome Shotgun Assembly

Whole Genome Shotgun Assembly. Two strategies for sequencing: clone-by-clone approach whole-genome shotgun approach (Celera, Gene Myers). Shotgun sequencing was introduced by F. Sanger et al. (1977) and has remained the mainstay of genome sequence assembly for nearly 25 years now.

Molecular Evolution

Molecular Evolution. Lecture 3. Origins of variation: mutation. Different molecular regions, different rates. DNA distant from genes evolves very quickly (at about one substitution per 10 8 years), Flanking regions upstream and downstream from a gene evolve less quickly than that,
