Antibiotic Resistance

Question 1

Mutation

Answer 1

Rare, random change in an organism’s DNA that can be inherited.

Change the sequence of the DNA bases in a gene which produces a genetic variant.

Question 2

Enzymes

Answer 2

proteins which need an active site with a very specific shape to be able to work properly

Question 3

Process of evolution in antibiotics

Answer 3

There is variation in the characteristics of organisms within the species

Changing conditions in the environment favours one particular form of the species

The frequency of the favoured form increases under these conditions. Survival of the fittest

The frequency of the less well adapted form decreases under these conditions

Over time, the gene that increases survival will become more common in the population making more bacteria antibiotic resistant

Question 4

The problem with antibiotic resistance

Answer 4

• This is a problem is someone gets infected with this bacteria, because they are not affected by antibiotics.These are called superbugs. It is becoming more common.
