Welcome to Genetics

Genetics is a very modern field of Biology where new discoveries and new techniques are being made that will revolutionise our lives. It is the science of genes, heredity and variation. Topics include:

  • DNA
  • cell division by either mitosis or meiosis
  • protein synthesis
  • genetic modification

    • DNA & chromosomesDNA double helix and bases; chromosome types (haploid, diploid).
    Genetic ModificationModification by selective breeding and genetic engineering e.g insulin production.
    InheritanceAlleles, inheriting characteristics, gender and disorders (cystic fibrosis, Polydactyly).
    Mitosis and MeiosisHow cells divide by either mitosis or meiosis (for haploid gametes).
    Protein SynthesisTranscription (DNA to mRNA) and translation (tRNA, ribosome, amino acid, polypeptide).
    MicropropagationGrowth of plantlets from an exaplant in vitro to produce a clone.
    CloningTechnique and ethical concerns of cloning, don't forget Dolly the Sheep!
    Artificial InseminationCollection and storage of semen, how insemination is performed and advantages of AI.
