| Summary |
Reveals the genetic code and how DNA expresses itself in the chemistry of life.. Covers how DNA codes for proteins and how it expresses the code.. DNA is extracted in the laboratory.. DNA codes for proteins.. Refresher on proteins and their roles.. DNA is a triplet code for proteins.. Transcription of DNA to mRNA.. Translation of mRNA via tRNA to polypeptides - all animated.. The universal genetic code and a brief demonstration of how we can read the code in the laboratory.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? |
