B1 - You And Your Genes
  1. What is your Genome?
    1. Humans,other animals, and plants look a lot like their parents.This is because they have inherited genetic information from them.This information controls how an organism develops and functions.It is stored in genetic material. All the genetic material of an organism is called its genome
      1. You can some features that are effected by the environment e.g. a scar. Almost all of your features are affected by both the genetic information you inherited and the environment.
        1. For example, your your height and body mass because you keep growing and changing this is effected by the environment and what you do ! You weren't born with just one size body mass and you don't stay the same height. It changes.
        2. Eukaryotic organism - it's a type of organism that has cells with a nucleus and organelles with membranes. Includes all animals, plants, fungi and protists.
          1. Prokaryotic organism - it's a type of organism that is made up of cells that do not have a nucleus or organelles with membranes.Such as bacteria.
            1. Some bacteria contain small loops of genetic material. Each loop is caled a plasmid. Plasmids can be used in genetic engineering.
            2. If you could see inside the nucleus, you would see the genetic material. It is stored as long threads called chromosomes
              1. There are 46 chromosomes in a nucleus of a human body cell.Chromosome are in pairs; in a human cell there are 23 pairs. Chromosomes are made up of very long molecules of DNA
            3. What is DNA?
              1. The structure of DNA was discovered in 1935 by James Watson and Francis Crick.
                1. The DNA consists of two strands that are twisted together to form a double helix.
                  1. Each strand of DNA is a long molecule made from lots of small molecules joined together in a chain. The small molecules are called nucleotides.
                  2. DNA is an example of a natural polymer. A polymer is a long chain molecule made from lots of small molecules, called monomers, joined together. Nucleotides are monomers that join together to make the DNA polymer.
                  3. What are Genes?
                    1. A gene is a region of DNA
                      1. Each of your chromosomes contain many genes.
                        1. Genes contain the instructions that cells use to make proteins. Each cell nucleus contains the instructions for making every protein in the human body
                        2. What are proteins?
                          1. Proteins are important Molecules
                            1. There are many different proteins, which can be :
                              1. structural - for example collagen (a protein found in connective tissues)
                                1. functional - for example amylase (an enzyme that speeds up chemical reactions)
