DNA deoxyribonucleic acid Large membrane bound organelle inside

DNA (deoxyribonucleic acid) Large membrane bound organelle inside a cell that contains genetic material. Gene Reproduction from one cell of a parent organisms by simple cell division, without fertilisation of gametes. Questions on mitosis What are three uses of cell division by mitosis? Questions on meiosis What is the purpose of cell division by meiosis? A normal body cell contains 46 chromosomes - just before mitosis the chromosomes copy themselves. How many chromosomes are there now in the cell? How many daughter cells are produced by meiosis? How many chromosomes do human cells produced by meiosis contain? How many daughter cells are produced by mitosis? Are the daughter cells produced in meiosis genetically identical or different to the parent cell? Chromosome A form of cell division that produces two cells genetically identical to the parent cell. Are the daughter cells produced in mitosis genetically identical or different to the parent cell? Nucleus Production of offspring by the fusion of male and female sex cells (gametes). How many parents are involved in asexual reproduction? How many times does the parent cell divide in meiosis? How many times does the parent cell divide in mitosis? What is the name given to sex cells produced by meiosis? Mitosis The genetic material found in the nucleus of living cells. Chromosomes are made of DNA and a gene is a section of a chromosome Meiosis A specialised sex cell, such as sperm or eggs, involved in sexual reproduction. Asexual Reproduction Sexual reproduction Stem cells Gametes Small section of DNA in a chromosome. Each gene contains the code for an inherited characteristic by making a particular protein. A type of cell division to produce gametes. Two divisions of the original cell produce four cells with half the normal number of chromosomes. A long molecule of DNA containing many regions called genes. They are found in the nuclei of cells. A cell that, unlike most body cells, can divide and differentiate into other cell types. Purpose of cell division Number of daughter cells produced Number of chromosomes found in the daughter cells Number of divisions Genetically identical (clones) or genetically different daughter cells? Where this type of cell division takes place Mitosis Meiosis Growth, repair and asexual reproduction Produce gametes
