Below are selected objectives from the Y13 biology programme that link tothis seminar.
You should review these concepts before the seminar.

Molecular Genetics / Mutations  Please remember these are only the objectives linking to this seminar—refer to your unit hand out at school for a full list

  • Describe DNA in terms of structure and function
  • Describe the process of DNA replication and the role that enzymes have in this process
  • Describe the process of protein synthesis and the role of DNA and enzymes in the production of proteins
  • Describe the role of DNA in gene expression and the determination of phenotype
  • Describe the control of gene expression at the transcriptional level in prokaryotes and eukaryotes
  • Describe the role of metabolic pathways in the control of gene expression
  • Describe the process if mitosis and meiosis.
  • Define the term mutation and identify ways in which mutations may affect an organism
  • Identify the causes of mutations
  • Differentiate between somatic and gametic mutations and identify the potential effect of each of these.
  • Show understanding of molecular genetics by using the core knowledge to give reasons for events that happen in the cell and link ideas
  • Show understanding of the cause and effect of mutations by using the core knowledge to link ideas

Biotechnology Please remember these are only the objectives linking to this seminar—refer to your unit hand out at school for a full list

Describe the techniques involved in gene cloning and how gene cloning meets human needs and demands.

  • Describe the techniques involved in transgenesis and how transgenesis meets human needs and demands.
  • Describe the techniques involved in DNA profiling and how DNA profiling meets human needs and demands.
  • Describe the techniques involved in genome analysis and how genome analysis meets human needs and demands.
  • Describe the technique of tissue culture and how it meets human needs and demands.
  • Be aware of the differing viewpoints of the use of biotechnological applications.
  • Show understanding of applications of biotechnological techniques by using core knowledge to link ideas


Challenge Question

Each year in New Zealand, approximately 2,400 women and 20 men are diagnosed with breast cancer and approximately 600 people die of breast cancer. 1 in 9 NZ women will be affected by breast cancer in their life time. Biotechnologies play a major role in the quest to understand cancer at a molecular level which can lead to the development of effective treatments. Technologies used in cancer research include:

  • gene profiling
  • genome analysis
  • gene cloning and transgenesis
  • cell culture

The Human Genome Project has provided extensive information which allows scientists to look at genetic differences between individuals. Microarray technology combined with this information allows scientists and clinicians to look at genetic differences between individuals and develop individualised therapies.

Discuss how the use of named biotechnologies has enabled scientists to develop understanding of cancer at a molecular level and how this understanding can then be used in the development of effective treatments.

Discuss this  You are encouraged to discuss possible these questions on the discussion page.
