transformation (genetic transfer) Flashcards
1
Q
transformation
A
cells take up dna extracellularly
2
Q
1st step of transformation ex. “ harmful bacteria”
A
body destroys some of the bacterial cells—> which causes cell to release some of its chromosomal dna (naked dna)
3
Q
naked dna
A
chromosomal dna released from cell
4
Q
2nd step of transformation
A
competent cell takes up bacteria released from the “harmful” bacterial cell
5
Q
3rd step of transformation
A
now have “harmless” bacterial cell with DNA from “harmful” bacterial cell
6
Q
result of transformation
A
“harmless” cell may now be able to produce harmful proteins
7
Q
significance of transformation
A
ex. streptococcus phalmonae
inluenza type b
menistidis
