Answer:
The drugs will need to target the genes and proteins that are responsible for the process of mitosis, The drugs could target the promoter regions of proto-oncogenes, that spur mitosis, and make them inaccessible to RNA polymerase. This will reduce the number of cyclins D1 and CDK4 & CDK6 that ‘floor the gas pedal’ on mitosis. These cancer drugs could also increase the expression of tumor suppressor genes by RNA polymerase hence increasing the number of tumor suppressor proteins that ‘put the brakes’ on mitosis.

Down feathers help to keep a bird warm by trapping air close to the body, which insulates the bird from the cold.
