| Summary |
Considers the master molecule, and how it stores information and copies itself.. Introduces Mendelian genetics and the basic capabilities of DNA.. Overview of mitosis and meiosis.. A thumbnail sketch of Mendel's key experiment - smooth peas and wrinkled peas.. Are chromosomes the Mendelian factors? No.. The search for 'genes' finds that DNA is the genetic material.. Chemical structure of DNA.. How DNA reproduces.. Demonstration of polymerase chain reaction.Atoms Alive is a series about DNA and genetics, which has been produced to support the biology curriculum for upper secondary students.It seems incredible that all life on earth comes from the information held in a single kind of molecule. DNA is an immense molecule that can direct the fantastically complex chemistry of the cell, reproduce itself, and even self-modify to take advantage of new conditions. You could say that all the different forms of life, from earliest to modern, are simply the different disguises of DNA as it has tried out many containers for itself. How is it conceivable that a molecule made of only four types of building blocks can create such sophistication? |
