DNA, genes and chromosomes are the structures containing the genetic material of humans. Find out about these structures, what happens to them during cell division or meiosis, and how genetic material is inherited. This programme contains diagrams of the DNA molecule and processes such as cell division and the use of Punnett Squares to predict offspring ratios.
Hank introduces us to that wondrous molecule deoxyribonucleic acid - also known as DNA - and explains how it replicates itself in our cells.
Issues of genetics and DNA are constantly cropping up in the news from food production and health, to legal cases and ethics. We hear about DNA in movies like Jurassic Park and X-men, we learn bits and pieces about it from TV shows like Dexter and and CSI, but what exactly is DNA, and how does it work? This animated short film has been made for those wanting a simple introduction (or even a refresher) on how DNA creates a living creature. In this video you will learn a bit about genetic code, DNA transcription and translation, and the importance of proteins in the chemistry of life.
Explore DNA structure/function, chromosomes, genes, and traits and how this relates to heredity! Video can replace old DNA structure & function video and in addition covers foundational concepts of heredity.
Scientific American editor Eric R. Olson untangles the relationship between the most fundamental components of our biology.
What exactly is DNA? This seemingly simple polymer, made up of just four different types of monomers, serves as the genetic material for all living organisms. For example, your DNA provides instructions for building and maintaining your unique body and can be passed on if you have children. Learn more about the discovery, structure, and synthesis of this remarkable molecule.
