There are more than 1 correct answers in the other choices. a potential chain terminator for the replication of RNA viral genomeQuestion 23 options: A newly discovered colon cancer cell line is established from a tumour sample derived from a patient with colon cancer. To understand more about this cell line and how it is different from normal cells, some experiments on the cell cycle of the colon cancer line are carried out. The cells are examined under the phase contrast microscope and the length of mitosis was found to be 90 minutes. Next, a DNA marker is used to find out how long DNA synthesis takes and indicates that DNA synthesis takes 3 hours. There is a gap between DNA synthesis and mitosis of 3.5 hours and a gap between mitosis and DNA synthesis of 4 hours. What is the total length of the cell cycle? _____ hours?
