Summary Discusses regulation of genetic expression, and mutation.. How genes are controlled or 'regulated'.. Cloning versus sexual reproduction.. Changes to the DNA - good and bad.. If all cells in an organism share the same genome, why aren't they all alike?. We look at examples of totipotency.. Any random change to a gene is a mutation; good, bad and neutral mutations. Oscar, the blind dog is a case of a double recessive mutated gene.. Sexual reproduction mixes genes.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?
