Inheriting Characteristics L.O: To understand how we inherit characteristics from our parents Peter Griffin Lois Griffin Meg Griffin Chris Griffin Stevie Griffin What features do Lois and Meg share? How are they different? What features do Peter and Chris share? How are they different? 1. Label pictures to describe the contents of the nucleus in terms of chromosomes, genes and DNA 2. Explain what genes do 3. Explain why parents have similar characteristics to their offspring in terms of gametes and genes Extracting DNA from kiwi 1. Add 10ml of washing up liquid to a jar, to that add 100ml of water 3g of salt 2. Add finely chopped kiwi to the jar 3. Shake the jar for 30secs then leave for 15mins 4. Do the worksheets while you are waiting 5. Filter the mixture after 15mins 6. Put 5ml of the liquid into a boiling tube add 5ml of cold ethanol down the side of the tube 7. After a minute white strands will appear in a layer this is the DNA • In as much detail as you can describe how we inherit features from our parents Keywords you must try to include: Sperm, egg, gametes, genes, nucleus, chromosomes, DNA, Fertilization animation FLASH 6 – Fertilisation FLASH 2 – Mitosis drag & drop Write a definition for each of the keywords whilst we go through the slides: • • • • • Gametes Nucleus Chromosomes genes DNA What is in a cell? The gametes • Are the sperm and egg cells • They contain half the genetic information of a normal body cell • When joined together the fertilised egg will have a complete set of genetic information The Nucleus • All body cells have a nucleus. • The nucleus contains all genetic information • Is said to be the “brain” of the cell as the genetic information controls what the cell does • The nucleus contains 23 pairs of chromosomes The chromosomes • A human cell contains 23 pairs of chromosomes, you have 2 of each chromosome (unless you’re a boy) • This means there are 46 chromosomes in total • You inherit half your chromosomes from your mother and half from your father. Making 23 pairs. • Chromosomes carry genes The genes • Genes or groups of genes code for your characteristics • Genes are made up of short lengths of DNA • DNA stands for Deoxyribose Nucleic Acid • In the 1950’s Watson and Crick were the first to come up with the structure of DNA • On each chromosome of the pair there can be different version of the same gene, i.e. blue or brown eyes • The variations are known as “alleles” What is DNA? Chromosomes and their genes are made of a molecule called DNA. DNA stands for deoxyribonucleic acid. Each chromosome is a very long molecule of tightly coiled DNA. DNA molecules carry the code that controls what your cells are made of and what they do. Which part of a DNA molecule holds this information? Structure of DNA Variation – what causes it? Two things – Genetics & Environment Genetic variation • You get ½ your genes from your mum & ½ from your Dad • So you have some characteristics in common with both parents but you look different too - VARIATION What’s the order? © Boardworks Ltd 2004
