GENOME PROJECT

• Berkeley Drosophila Genome Project, The FlyBase

Consortium, Celera Genomics

• First published in the March 24, 2000 issue of

Science.

• Assembly:Jul 2014

• Until now 6 notes have been released

• The genes that was annotated by BDGP included

coding genes, pseudogenes, and non-coding RNA

genes.

• The project can be followed from fruitfly.org

SEQUENCING(WHOLE GENOME SHOTGUN)

(Ellie McCosker,(2012) Genome sequencing vs. Genetic fingerprinting)

DIRECTED SEQUENCING STRATEGY WHICH WAS

FOLLOWED BY BDGP

(Gerald M. Rubin, The Drosophila Genome Project, Genome Research 6: 71-79, 1996)

For drosophila geneome project, the DNA of was sheared three times, altough

it is done with one shearing at WGS

A: transposable elements B:declared gap from release 2

C: comparisan of the gaps between release 2 &3

D: gaps at release 3

(The graphical illustration was taken from Susan C. et al 2002)
