Antibiotics

Question 1

What is vertical gene transmission

Answer 1

From one generation to another

Mitosis

Question 2

What happens when a course of antibiotics are not completed

Answer 2

Increases the chance of bacteria resistance
Most resistant survive
They are no longer competing for resources, therefore more likely to reproduce

Question 3

How do antibiotics work

Answer 3

1. Prevents bacteria from making normal cell walls by preventing peptides being made in cross linkages
   (When water enters bacteria it results in bursting)
2. Stop forming proteins/ forming abnormal proteins
3. Inhibits DNA replication
4. Disrupts cell membrane

Question 4

What is horizontal gene transmission

Answer 4

1. A conjugation tube forms
2. Plasmid of donor cell starts to replicate
3. Replicated plasmid starts to enter tube
4. Linear strand enters recipient cell
5. Linear strand forms a circle (plasmid)
