BI226 2009 Section 4: Ma pping genes in bacteria and bacteriophages
· Many important genetic concepts were discovered first in bacteria. Bacteria also serve
as tools for practical ap plications of genetics.
· Most bacterial genes are found on a circ ular DNA molecule called the bacterial
· DNA may be transferred from one bacteria l cell to another where transferred DNA
recombines with the chromosomal DNA.
. DNA transfer and recombination are used to map bacterial genes.
