A single colon epithelial cell acquires homozygous loss-of-function mutations in a key tumor suppressor gene, transforming it into a malignant cancer cell that divides once every 151515 hours.
Starting with this single mutated cell, how many cancer cells will be present after 303030 days? Assume that none of these cells die and that the rate of division remains constant.
Give your answer in standard form.
21 exam-style questions on AQA A Level Biology Gene expression is controlled by a number of features (A-level only), covering Most of a cell's DNA is not translated (A-level only), Regulation of transcription and translation (A-level only), and Gene expression and cancer (A-level only). Each one has a worked solution and a mark scheme showing where the marks go.
