  • 4.1: DNA Structure
    This chapter on DNA is presented by design short. It is intended to give a cursory overview. More details on nucleic acid structure and its role as the carrier of genetic information can be learned from courses and textbook on Molecular Biology. This guide is intended to give a cursory overview of this complicated field.
  • 4.2: The Central Dogma of Biology
    DNA must be duplicated in a process called replication before a cell divides. The replication of DNA allows each daughter cell to contain a full complement of chromosomes.
  • 4.3: The Language of DNA
    In this short chapter you will learn how modern molecular biologists manipulate DNA, the blueprint for all of life. The four letter alphabet (A, G, C, and T) that makes up DNA represents a language that when transcribed and translated leads to the myriad of proteins that make us who we are as a species and as individuals
