- Explain what happens at each phase of cell cycle: -DNA replication (when, where, how? Use terms such as DNA polymerase, complimentary base pairs) -Interphase (G1, S, G2) -Mitosis (overall goal of prophase, metaphase, anaphase, telophase, cytokinesis)arrow_forwardDescribe interphase, and identify its stages.arrow_forwardDescribe the events of the cell cycle, including interphase, mitosis, and cytokinesis.arrow_forward
- Briefly describe the structure and function of these cellular structures/organelles: endoplasmic reticulum, ribosomes, Golgi apparatus, mitochondria, lysosomes, peroxisomes, cytoskeleton, cell fibres, centrosome, centrioles, and cell extensions.arrow_forwardDetermine the interphase stage of the cell.arrow_forwardMitosis and cytokinesis are often referred to collectively as “cellular division.” Why are they more accurately called cellular replication?arrow_forward
- Define Commitment to the Cell Cycle and DNA Replicationarrow_forwardWhich of the following best describes the difference between interphase and mitosis? a) During interphase, DNA has a loose structure that condenses during mitosis. b) During interphase, histones help compact DNA into chromosomes. And once mitosis starts, histones are destroyed. c) During interphase, DNA is tightly packed into chromosomes that uncoil once mitosis starts. d) During interphase, DNA is packed as chromosomes. And during mitosis, DNA is called chromatin.
