2.4- disruptions to the cell cycle causes disease Flashcards
Cancer
a disease in which abnormal cells divide uncontrollably as a result pf failure oof cell cycle regulation
Proto-oncogenes
stimulate cell division, when mutated become cancer causing oncogenes
Tumor suppressor
prevents cancer by slowing down cell division
Physical Mutagen
cause DNA damage through physical factors, often leading to structural changes in the DNA molecule
Examples of physical factors
heat, ionizing radiation (x rays, gamma rays)
Chemical Mutagent
alter DNA structure by interfering with base pairing, causing incorrect DNA replication
Examples of Chemical factors
smoking, gas
Biological Agent
living organisms or viruses that alter DNA by inserting their genetic material into the host genome
Examples of biological factors
Viruses, Bacteria
