Syllabus Details:
Understandings
The nucleic acids DNA and RNA are polymers of nucleotides
DNA differs from RNA in the number of strands present, the base composition and the type of pentose
DNA is double helix made of two antiparallel strands of nucleotides linked by hydrogen bonding between complementary base pairs
Application and Skills
Crick and Watson’s elucidation of the structure of DNA using model making
Drawing simple diagrams of the structure of single nucleotides of DNA and RNA, using circles, pentagons, and rectangles to represent phosphates, pentoses and bases
Rosalind Franklin and Maurice Wilkins’ investigation of DNA structures by X-ray diffraction
