9.7 Option – Genetics: The Code Broken?

Contextual Outline

Science has come a long way since Mendel’s important work on identifying the transmission of inherited factors across generations. The code for transmitting this genetic information has been identified and models have been developed to explain gene functioning. Transcription of the information into functional proteins is now well understood and models are being developed to test how genes direct the structure, function and development of an organism.

Modern genetics is moving towards an increased understanding of the biochemical role of individual genes. This is being enhanced by the Human Genome Project that has sequenced the entire human genome to identify all the encoded genes.

This module increases students’ understanding of the nature, practice, applications and uses of biology, the implication of biology for society and the environment, and current issues, research and development in biology.

    Neurospora (Fungus) 14 When scientist say that all living organisms share a universal genetic code it means DNA is called the universal genetic code because the structure and components of DNA are that all living organisms are related in some type of way. The universal genetic code relates to the hypotheses of life on earth by showing life originated from a single ancestor, the genetic code has more or less remained consistent. Life is a molecule that can rebuild itself, RNA-polymerase…

While some people claim that is inhumane, families who had to deal with dangerously ill patients at least had a choice and knew where the patient was and that there would be some kind of treatment.
