Bacterial Genetics Flashcards
1
Q
Ribosomes euk vs. pro
A
Pro - 70S
Euk - 80S
2
Q
Conjugation
A
Bacterial sex…cell to cell contact needed
Donor cell attaches to receipient with its pillus
Cells contact one another
One strand of plasmid transfers to recipient
Recipient synthesizes a complementary strand
3
Q
Plasmid
A
Extrachromosomal DNA
4
Q
Transformation
A
Take up DNA from the environment
Recombination occurs between donor and recipient DNA
5
Q
Tranduction
A
Phage infects donor
Phage DNA and proteins made and bacterial chromosome broken down
Bacterial DNA is packaged in the phage capsid
Phage carrying the bacterial DNA infects a new host cell
Final cell is different from both the donor and recipient
6
Q
Transposition
A
Transposons can move autonomously through DNA…can jump from plasmid to chromosome, etc.
