This course offers a gentle introduction to DNA and the cells that make us, subjects which have enormous impacts on our health and daily lives. It is a repeat of last year's course. What is DNA and how were its structure and roles in heredity identified? How was its code cracked and how is it decoded in our body's cells? How does a single fertilized egg become trillions of cells and why aren't they all the same? What are stem cells and why do they matter? What are viruses and how do they hijack our cells? How do diseases such as cancer and dementia arise and what can we do about them? The explosion in knowledge of cells and DNA is transforming medicine, forensic science and agriculture. This course aims to provide an intelligible introduction for beginners.
Note:There will be no class in February half-term, date tbc.
