Learn how scientists discovered DNA and determined its function, composition, and structure - and how they experimented with cloning Dolly the sheep!
Learn how nucleotides combine to form the double helix structure of DNA - the complex molecule that serves as the foundation for all living organisms.
What is DNA replication? Learn how nucleotides bind to form new strands of DNA - creating a replica (or identical copy) of a cell’s genetic material.
Confused about the relationship of DNA to RNA, or RNA to a specific amino acid? Sit back, relax, and brush up on the basics of RNA and protein synthesis.
In this second installment in the biology series on RNA, learn about the first stage of protein synthesis: the four-step process of transcription.
