How is an hfr chromosome formed
WebBioengineershave created F plasmids that can contain inserted foreign DNA; this is called a bacterial artificial chromosome. The first DNA helicaseever described is encoded on the F-plasmid and is responsible for initiating plasmid transfer. It was originally called E. coliDNA Helicase I, but is now known as F-plasmid TraI. WebF’ cells are formed from Hfr cell during induction of F- factor from chromosomal DNA in which F-factor carries a portion of chromosomal DNA along with it.In the cross (conjugation) between F-prime (F’) cell and F- cell, frequency of recombination is high as well as frequency of transfer of whole F-factor is also high.
