Cell Cycle: Mitosis Process in which the nucleus divides Replicated DNA is separated into two sets, one for each future daughter cell Describe what is happening in each stage (A – D). Use the terms “chromosomes” and “sister chromatids” in your description.

Mastery Check 9 Which of the following describes what happens during mitosis?   A The nucleus divides and then the DNA replicates. B The DNA breaks apart and new nucleotides match the original nucleotides. C The cytoplasm divides completely and 2 new cells are formed. D The two copies of DNA are separated into 2 different nuclei.

Cell Cycle: Cytokinesis p.11 Cell Cycle: Cytokinesis Final phase of cell cycle (right after mitosis) The rest of the cell splits into two Cytoplasm is split (along with other cell components within it) as the cell membrane pinches in, between the two new cell nuclei

Cell Cycle: Summary Match the cell cycle stages in the table below to the letters/numbers on the Cell Cycle diagram. A B C D 5

Cell Cycle: Summary Write your summary of what you think are the most important concepts of the cell cycle.

You should be able to: Describe the stages of the cell cycle, including deoxyribonucleic acid (DNA) replication and mitosis, and the importance of the cell cycle to the growth of organisms.

Model Evaluation Compare pros & cons of these two DNA models: p.12 Model A Model B

Mastery Check 11 1. The diagram above shows a 2-dimensional model of DNA. This model is good because –   A the rungs of the ladder are made up of nitrogen bases and phosphates B adenine is paired with guanine C the double helix shape is illustrated D thymine is paired with cytosine
