D1.3.8 (HL)—Gene knockout question 1
[Maximum number: 1]
Knockout organisms are used as models in research. The p53 knockout mouse is named after p53, a gene which codes for a protein that normally suppresses the growth of cancerous tumours.
How could scientists use p53 knockout mice in cancer research?
A
To extract tumour suppressor protein from p53 knockout mice for cancer treatments
B
To obtain functional copies of the p53 gene to use in gene replacement therapy
C
To investigate the effect of new anti-cancer drugs on mouse tumours
D
To study the effect of mutations on the expression of the p53 gene
