The Cell Cycle and Cell Division

1. The Cell Cycle and Cell Division. What do you think?. Cell division produces two identical cells. Cell division is important for growth. At the end of the cell cycle, the original cell no longer exists. 1. The Cell Cycle and Cell Division. Do you agree or disagree?. 1.

The cell cycle and cell division

The cell cycle and cell division. Why is it called the cell cycle ?. Before the cell can divide, DNA must be copied. Semiconservative- one old strand, one new strand Increases accuracy. After replication. The life cycle of a cell. G1 can last for a few minutes or decades.

The Cell Cycle

The Cell Cycle. 1/27/12. Objective: Understanding the components of the cell cycle Do now: Do the hokey pokey, turn yourself around. Do later: Draw a cell going through the four phases of mitosis, and label the major events in each phase. Quiz time!.

The Cell Cycle

CONSISTING OF INTERPHASE ,MITOTIC PHASE, & CYTOKINESIS. The Cell Cycle. The Mitosis Puzzle. Lay blank sheets lengthwise to each other and tape them together. Write Interphase, Prophase, Metaphase, Anaphase, & Telophase across the top of the sheet.

The Cell Cycle

The Cell Cycle. The “life span” of a cell can be broken up into 3 distinct parts While distinct, note that the stages occur continuously, one after another. Interphase. Longest phase Also called the resting phase

The Cell Cycle

The Cell Cycle. Imagine your skin…. Cells have a life cycle. It goes from birth…to birth…to birth…to birth… Is there death? Eventually… Cells (most human cells at least) are limited in the number of times they can reproduce.

The Cell Cycle

The Cell Cycle. Why are cells so small??. What limits the size of a cell?? Most cells are between .002 - .2 millimeters. What limits the size of a cell?. Diffusion Very fast and efficient over short distances Becomes slow and inefficient as the distances become larger

The Cell Cycle

The Cell Cycle. Sections 5.1-5.2. The cell cycle is a regular pattern of growth, DNA replication, and cell division. Four Main Stages. The cell cycle has four main stages: Gap 1 (G1) Synthesis (S) Gap 2 (G2) Mitosis (M) Prophase Metaphase Anaphase Telophase Cytokinesis. Interphase.

The cell cycle

The cell cycle. The Cell Cycle. Interphase – Three phases. G1 – Growth & ordinary cell processes S – DNA is copied (replication) G2 – Organelles are copied. Mitosis: First phase - prophase. DNA supercoils. Prophase (continued). Nuclear membrane breaks down

THE CELL CYCLE and CELL DIVISION

THE CELL CYCLE and CELL DIVISION. Think about it… why do cells stay small?. DNA Overload = Limit to Cell Growth. The information stored in that DNA is able to meet all of the cell’s needs in a small cell If a cell grows too large, the DNA cannot produce enough proteins to supply the cell.

Cell Division and the Cell Cycle

Cell Division and the Cell Cycle. The Cell Cycle. Interphase is the growth phase makes new molecules that increase the cell volume DNA is copied during this phase consists of 3 parts, G1, G2 and S Division Stage consists of mitosis and cytokinesis. Stages of Growth Phase. G1 gap 1

The Cell Cycle and Cell Death

The Cell Cycle and Cell Death. SNC2D. Cell Reproduction. Mitosis in animal cells looks very like mitosis in plant cells:. Interphase. The cell prepares for cell division by growing (producing new proteins and organelles) and by synthesizing copies of its DNA (the chromatin). Prophase.
