- 4. Figure below shows drawings of a cell at various stages in the mitotic cell cycle. A B E (a) List the letters shown in figure above in the order in which these stages occur during a mitotic cell cycle. [2] (b) Explain what is happening in stage D in figure above. [2]1. Growth factors stimulate the cell to enter the G1 phase of the cell cycle. During this phase, the synthesis of enzymes that catalyze the formation of deoxyribonucleotides (dNTPs) is induced. In what process are these substrates used in the S phase of the cell cycle? To answer the question: a) Draw a scheme of the process in which deoxyribonucleotides are substrates; b) name the enzymes, indicate their role and the biological significance of the process.13) A phosphotase removes an inhibitory phosphotyrosine phosphate from the serine protein kinase, in MPF whcih activates the kinase and triggers the initiation of mitosis. true or false
