Gene transfer mechanisms of bacteria

Question 1

Antibiotic resistance will kill

Answer 1

90000 brits by 2050

Question 2

Texiobactins are a potential way

Answer 2

to combat antibiotic resistance

Question 3

CBG from cannabis could be a

Answer 3

method of fighting antibiotic resistance

Question 4

Electron microscopy could be used

Answer 4

to visualise a plasmid.

Question 5

Plasmids can be

Answer 5

relaxed (open- circular) or supercoiled (see pic of slide)

Question 6

Topoisomerases cause the

Answer 6

DNA to be supercoiled and they can also be used to relax the DNA

Question 7

Sedimentation analysis works by

Answer 7

having a 5% sucrose solution at the top and a 20% sucrose solution at the bottom. A sediment solution will reach the bottom if it is reasonably sediment. A compact molecule sediments more faster than a open circular piece of DNA.

Question 8

Plasmid encoded functions

Answer 8

are highly diverse (see pic of slide)

Question 9

the resistances of drugs were brought about from

Answer 9

plasmids

Question 10

If a bacteria was able to pick up a plasmid which has drug resistant genes,

Answer 10

the bacteria become immediately resistant.

Question 11

Plasmids encode for

Answer 11

a different variety of properties
