Question

A scientist is trying to discover a new treatment to stop cancer cells from dividing. In the cancer cells, which of these processes will stop if the treatment is successful?


A mitosis
B chemosynthesis
C binary fission
D genetic recombination

Answer 1

A only.

Mitosis is the dividing of cells into genetically identical copies. This is what cancer cells ( and indeed, most non-sexual cells in your body) do.

Chemosynthesis is the production of chemicals inside the cells. If the treatment is designed to stop them reproducing, this will not stop.

Binary fission is a form of cell division carried out by prokaryotes, aka simple single-celled organisms. Human cells, cancerous or not, do not do this.

Mitosis is the direct copying of genetic information, so genetic recombination does not happen anyway. Only in the production of gametes, meiosis, does genetic recombination occur.

Answer 2

and? atleast i gave him more info
