Exploring DNA Structure and Function

The video introduces the seventh unit on DNA, covering its structure and function. It explains DNA as a blueprint for protein synthesis, highlighting the roles of Watson, Crick, and Franklin in discovering its structure. The video details nucleotides, base pairing, and the double helix structure, emphasizing the importance of hydrogen bonds. It also discusses the DNA backbone and codons, which determine amino acid sequences for protein formation. The lesson concludes with instructions for completing vocabulary questions using the provided notes.
