Vaccines and Antibiotics

Question 1

The antibiotic has been made that binds to ribosomes in bacterial cells. Explain how this causes the death of bacterial cells.

Answer 1

It will prevents protein synthesis so enzymes are not produced

Question 2

Give one way in which antibiotics can prevent the growth of bacteria

Answer 2

Prevent cell wall formation
Causes cell lysis
Prevent DNA replications

Question 3

Describe how bacteria can become resistant to antibiotics by vertical gene transmission.

Answer 3

Genes transmitted through cell division

REJECT mitosis

Question 4

In cells, taxol disrupts spindle activity. Use this information to explain the results in the group that has been treated with taxol.

Answer 4

In mitosis the spindle fibres cannot attach to the chromosomes so cell division slows down

Question 5

Describe how gene transmission and selection have increased the difficulty of treating bacterial infections with antibiotics.

Answer 5

Resistant bacteria have an antibiotic resistant gene is passed down through vertical gene transmission. This bacteria will survive increase the resistant population.

Also passes the resistant gene via horizontal gene transmission were the plasmid replicates and gets passed to a bacterium through a conjugation tube.
