A recombinant vaccinia virus genome was constructed in which the viral thymidine kinase (tk) gene was … A high-frequency recombination cell (Hfr cell) (also called an Hfr strain) is a bacterium with a conjugative plasmid (for example, the F-factor) integrated into its chromosomal DNA. The integration of the plasmid into the cell's chromosome is through homologous recombination. A conjugative plasmid … Ver mais The Hfr strain was first characterized by Luca Cavalli-Sforza. William Hayes also isolated another Hfr strain independently. Ver mais An Hfr cell can transfer a portion of the bacterial genome. Despite being integrated into the chromosomal DNA of the bacteria, the F … Ver mais F-prime cell contains F-plasmid that integrates with the chromosomal DNA and carries part of the chromosomal DNA along with it while being excised from the chromosome.

In gene conversion, a section of genetic material is copied from one chromosome to another, without the donating chromosome being changed. Gene conversion occurs at high frequency at the actual site of the recombination event during meiosis. It is a process by which a DNA sequence is copied from one DNA helix (which remains unchanged) to another DNA helix, whose sequence is altered. Gene conversion has often been studied in fungal crosses where the 4 pro… east lake diamond sports
