DNA • What does DNA stand for? • DNADeoxyribonucleic Acid 100 DNA • What part of the cell contains the DNA? 200 DNA 200 • What part of the cell contains the DNA? • The Nucleus of all cells contain the genetic material (DNA) DNA • DNA is coiled up into... 300 DNA • DNA is coiled up into... • DNA is coiled up into Chromosomes. 300 DNA 400 • DNA molecules are made up of 3 parts; What are they? DNA 400 DNA molecules are made up of 3 parts; What are they? • DNA is made of a sugar, phosphate and a nitrogenous base. Or it has a sugar-phosphate backbone and nucleotide bases. DNA 500 Explain how the nucleotide of DNA are paired and how they are read and made into proteins. DNA 500 Explain how the nucleotide of DNA are paired and how they are read and made into proteins The nucleotides on DNA are paired up A-T and C-G, these are later read during translation as a triplet or codon. Each triplet codes for an amino acid which when attached to other amino acids makes a protein. Mitosis • What is mitosis and where does it takes place? 100 Mitosis 100 What is mitosis and where does it takes place? • Mitosis is a process of cell division that happens in all non-sex cells. Mitosis 200 • What happens to the DNA in the early stages of Mitosis? Mitosis 200 What happens to the DNA in the early stages of Mitosis? • The DNA is replicated. Mitosis 300 • How many daughter cells are produced at the end of one mitosis division? Mitosis 300 • How many daughter cells are produced at the end of one mitosis division? • There are 2 identical daughter cells produced at the end of a mitotic division. Mitosis 400 • Why is mitosis the best sort of division to take place in non-sex cells? give an example of when mitosis occurs. Mitosis 400 • Why is mitosis the best sort of division to take place in non-sex cells? give an example of when mitosis occurs. Non sex cells need to be identical to each other, they are used for growth or replacement during injury or cell death, etc. Mitosis • List the stages of Mitosis in order and briefly describe what is happening in each. 500 Debtors & Creditors 500 List the stages of Mitosis in order and briefly describe what is happening in each. Interphase- Chromosomes Replicated Prophase- Double stranded Chromosomes are visible. Metaphase- Chromosomes line up. Anaphase- Chromotids separate to opposite ends of cell. Telophase- 2 new cells are formed. Meiosis • In which cells does Meiosis take place? 100 Meiosis 100 • In which cells does Meiosis take place? In gametes, sex cells. Meiosis 200 • How many cells are produced at the end of a meiosis division? 200 Meiosis • How many cells are produced at the end of a meiosis division? 4 Cells that are not identical to the parent cells. Meiosis 300 • Why is meiosis better than mitosis in sex cell division and later in the formation offspring? Meiosis 300 • Why is meiosis better than mitosis in sex cell division and later in the formation offspring? The offspring will have genetic information from both parents and when the sex cells combine the final zygote will contain the correct number of chromosomes. Meiosis • List and explain 2 differences between mitosis and meiosis. 400 Meiosis 400 • List and explain 2 differences between mitosis and meiosis. • 2 Stages of division. • 4 non identical cells produced versus 2 identical cells. • Final cells have haploid number of chromosomes versus diploid number in mitosis. Meiosis 500 • Using the white board, draw the process of meiosis from start to finish. Meiosis 500 • Using the board draw out the process of meiosis. Similar to page 185 in Links 4 Cells What is a cell? 500 100 Cells What is a cell? • A cell is the basic unit of living organisms, containing the genetic information for life. 500 100 Cells What are stem cells? 500 200 Cells What are stem cells? 500 200 • Stem cells are cells found in most, if not all, multi-cellular organisms. They are characterized by the ability to renew themselves through mitotic cell division and differentiating into a diverse range of specialized cell types. Cells 500 300 • What are chromosomes? Why are they important? Cells 500 300 What are chromosomes? Why are they important? It is a single piece of coiled DNA containing many genes, and other nucleotide sequences. The are important because they contain all the genes necessary for life. Cells 500 400 • A cancerous cell replicates infinitely, why is this a program? What mechanisms does you body have to try and prevent uncontrolled growth? Cells 500 400 A cancerous cell replicates infinitely, why is this a problem? What mechanisms does you body have to try and prevent uncontrolled growth? Cancerous cells are a problem because the negatively effect the body causing the spread of cancer and sometimes leading to death. In normal situations the body controls uncontrolled growth by having programed cell death that destroys malfunctioning, damaged or unnecessary Cells Explain the life cycle of a cell. 500 500 Inheritance • Explain the life cycle of a cell 500 500 Pot Luck 100 • How many chromosomes in a diploid or haploid? Pot Luck Haploid- 23 •Diploid- 46 • 100 • How many chromosomes in a diploid or haploid? Pot Luck • What is an amino acid? 200 Pot Luck • What is an amino acid? Building block of protein 200 Pot Luck • What is a genome? 300 Pot Luck 300 • What is a genome? Genome is the complete set of genetic information for a species. • Pot Luck 400 • What is RNA and what does it do? Pot Luck 400 • What is RNA and what does it do? RNA is ribonucleic Acid and is involved in copying the DNA before it is translated into protein. Pot Luck 500 • How can DNA be used in solving crimes? Where can someone’s DNA be found in a crime scene? How can we be sure that if someone's DNA is found that it is definitely them? Pot Luck 500 • How can DNA be used in solving crimes? Where can someone’s DNA be found in a crime scene? How can we be sure that if someone's DNA is found that it is definitely them? DNA is unique to each human, no 2 people have exactly the same DNA, so if someone’s DNA matches that of a crime scene it means they had to be there. DNA can be found in Hair, skin even saliva that someone may leave behind in a crime scene.
