PPT-Cell cycle, DNA, and replication

BIO LIFE THINK ABOUT THIS What do we do in our lifetime What are the major stages of our life What are the Major stages of physical development in our lives What would it look like. Mike Clark, M.D.. The . cell cycle. , or . cell-divisional cycle. , is the series of events that take place in a cell leading to its division and duplication (replication). . In cells without a nucleus (prokaryotes), the cell cycle occurs via a process termed binary fission. . Why do cells need to divide?. Growth and development. You started as 1 cell and now you’re made up of roughly 40 TRILLION cells. Repair and regeneration of tissue. Reproduction. What happens when cells divide? . The . cell cycle. , or . cell-divisional cycle. , is the series of events that take place in a cell leading to its division and duplication (replication). . In cells without a nucleus (prokaryotes), the cell cycle occurs via a process termed binary fission. . What is a virus?. Tiny, . nonliving. . particles that can . cause disease.. Remember the . 4. characteristics of life?. Viruses are NOT considered to be a living organism because:. They DO NOT . reproduce. Chapters 12 & 13. The Role of dna. Stores Information. Keeps the instructions that make you look and act the way you do. Copies Information. During cell division you have to copy the DNA before the cell can split. mutualism. .. A human red blood cell is placed in hypotonic water. Predict what will happen to the cell. .. Write the complimentary strand for this sequence:. . CTAAGTCGA. The Cell Cycle. How do our wounds and injuries heal?. In . their 1953 announcement of a double helix structure for DNA, Watson and Crick stated, . "It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material.". Cell Cycle - a cycle of growth, development, and division. This is how organisms grow, produce new cells, and replace old cells. The cell cycle occurs in 2 phases: Interphase and . Mitosis. The Cell Cycle: Interphase. Honors Biology. Mrs. Sims. Let’s Start with a Video. Please view the video before you start this presentation. . DNA Replication Animation. **This animation is created by McGraw Hill, the publisher of your textbook.. Get a sheet of paper and . number . 1-29. Answer are on the last slide. 1. were . credited for finding the structure of DNA. Chargaff. Franklin. Watson . & . Crick. 2. What phase of Mitosis is this?. Unit 1 – Cells and Proteins. Advanced Higher Biology. Miss Aitken. Why is controlling the cycle important?. Complex events must work perfectly to produce new daughter cells. Mutations can occur if events do not go to plan. DNA Structure Simulation. Before we begin, let’s investigate the way DNA molecules are set up!. http://learn.genetics.utah.edu/content/molecules/builddna/. The Structure of DNA. What is DNA?. A bit about DNA…. It is the growth and division of single cell into daughter cells and duplication (replication).. In . prokaryotic cells, . the cell cycle occurs via process termed binary fission.. In . eukaryotic cells, . Question #1. Looking at the diagram below, what would be the correct order of the illustrated stages of mitosis?. B-D-C-A. A-B-C-D. A-B-D-C. B-C-D-A. Question #2. The diagram below illustrates the stages of the cell cycle. Inhibitors stop the cycle at G1 to avoid cells dividing out of control. When mutations take place and do not allow the inhibitors to stop the cell cycle, what can happen in the body?.
