Document Summary
Bacterial cells can have their genetic info altered by dna polymerase that makes a mistake during dna replication. Chemicals and radiation can damage dna in bacterial cells and alter the genetic info in that damaged cell. How dna info can be passed from one organism to another will be discussed in this ch. From growth medium, from organisms from other cells. Pass info down from mother to daughter. A change in an organism"s characteristics because of transfer of genetic information. A process where cell can take up dna, only allows for small amount of dna to come in (only. Naked dna: dna that has been released from an organism after the cell is lysed and. Competence factor is released into the medium and apparently facilitates the entry of. Cell can pick up dna / make competence factor. Organisms has to make competence factor in order to transform; not all organisms can transform.
