Cell Cycle In the cell cycle, a precise sequence of events leads to the creation of new cells. The events are: Interphase Mitosis (including prophase, metaphase, anaphase, and telophase) Cytokinesis

Creating New Cells- the steps Page p29 Figure 1.10

Creating New Cells- the steps Remember the steps! Interphase Prophase Metaphase Anaphase Telophase Cytokinesis I Prefer Mice And Talking Cats

Copyright © 2010 McGraw-Hill Ryerson Ltd. New animal cells are created during the cell cycle. The nucleolus, is a structure composed of proteins and nucleic acids found within the nucleus. Chromatin condenses to form chromosomes.

Copyright © 2010 McGraw-Hill Ryerson Ltd. New animal cells are created during the cell cycle. Replicated chromosomes are also called sister chromatids. In animal cells, a pair of organelles called centrioles move to each end of the cell, forming poles of the miotic spindle.

Copyright © 2010 McGraw-Hill Ryerson Ltd. New animal cells are created during the cell cycle. Each chromosome is connected to a the spindle fibre at its centromere.

Cell Division – Uncontrolled! If a cell ignores a signal to stop dividing, unchecked cell growth can result. Over time, the newly divided cells form a mass called a tumour. A mutation (a permanent change in a cell’s DNA) is what causes the cells to ignore the “stop” signals. Cancer cells differ from normal cells in shape, size, and content.

Copyright © 2010 McGraw-Hill Ryerson Ltd. Cancer Cells Benign tumour cells tend to look normal. Cancer cells (malignant tumour cells) look much more “unusual”.
