Cancer

Question 0

Why are proliferation genes also known as proto-oncogenes?

Answer 0

When they mutate they form oncogenes which are found in many cancers.

Question 1

What are proliferation genes?

Answer 1

Genes that code for proteins which promote cell division only when an external signal is received.

Question 2

What happens when proliferation genes mutate?

Answer 2

Give proteins with abnormal shapes which stimulate EXCESSIVE CELL DIVISION and TUMOUR FORMATION even in the absence of any external signal.

Question 3

Are oncogenes dominant or recessive alleles?

Answer 3

Dominant

Question 4

What do anti proliferation genes do?

Answer 4

Code for proteins which restrict cell division by operating at the cell cycle checkpoints

Question 5

In which type of genes are mutations recessive?

Answer 5

Antiproliferation genes

Question 6

What is an oncogene?

Answer 6

Cancer causing gene; mutated proliferation gene
