BIO 214 Lecture Notes - Lecture 27: Prophage, Plasmid, Chromosome
Document Summary
Ways to transfer genetic material between bacteria. The transfer of the dna requires direct cell to cell contact between the two cells. The direct contact between the two cells which is obtained through the pili. Requires dna from one cell to the other cell. When an f factor (a plasmid) is transferred from a donor to a recipient, the recipient cell is converted into a f+ cell. The recipient is transformed into a f+ cell. One cell contains f plasmid while the other won"t. F- can not generate the sex pili. One strand of the f factor transfers through the sex pili into the f- cell. The f- cell is converted into the f+ cell. Sometimes the f factor dna will combine with chromosomal dna which is called high frequency dna. Information was covered in the laboratory portion of this course, not in lecture. The process which a virus transfers genetic material from one bacterium to another using bacteriophages.
