Stem Cells

Starter Define these words: Gene Locus Allele Mitosis Meiosis Homologous chromosomes Chromatid Diploid A.One of the two copies of a chromosome that are joined together by a centromere prior to cell division B. A type of cell division where the chromosome number is halved C.One of the different forms of a particular gene D.A section of DNA that codes for a polypeptide E.A type of cell division where the daughter cells have the same number of chromosomes as the parent cell F.A term referring to a nucleus which contains two pairs of chromosomes. G.A pair of chromosomes (one maternal and one paternal) that have the same gene loci. H.The position of a gene on a chromosome

Stem Cells Learning Objectives Define ‘Stem Cell’ Understand and give examples of how stem cells differentiate to form specialised cells Success Criteria (specification) Discuss the potential uses of stem cells in research and medicine Examples: repair of damaged tissues, treatment of Alzheimer’s and Parkinsons. Describe how stem cells might be used to research developmental biology
