Question
Dr. Serena Velazquez lands a coveted post-doc position at Johns Hopkins following completion of her MD/PhD in cancer therapeutics to treat late-stage pancreatic cancer using a mouse model. Her post-doc will be devoted to targeted mutagenesis of replicative enzymes to halt cell division in cancerous cells. She reviews mitosis and meiosis before reporting for her first day of work.
1) Cancer is essentially unregulated gene growth. Cancer cells sometimes have LOF mutations that affect the production of checkpoint proteins so nothing prevents the cells from continually moving forward and reproducing. If a LOF halted the cell cycle but DNA was still replicated, what check point was affected?
a) The G1 checkpoint.
b) The G2 checkpoint.
c) The G0 checkpoint.
d) The Metaphase checkpoint.
