Unit 12: Nucleic Acids
The structure of DNA allows efficient storage of genetic information.
Analysis of results of the Hershey and Chase experiment providing evidence that DNA is the genetic material.
The nucleic acids DNA and RNA are polymers of nucleotides.
Drawing simple diagrams of the structure of single nucleotides of DNA and RNA, using circles, pentagons, and rectangles to represent phosphates, pentoses and bases.
DNA is a double helix made of two antiparallel strands of nucleotides linked by hydrogen bonding between complimentary base pairs (in diagrams, helix does not need to be shown, but antiparallel does)
Rosalind Franklin and Maurice Wilkins' investigation of DNA structures by X-ray diffraction
Making careful observations - Rosalind Franklin's X-ray diffraction provided crucial evidence that DNA is a double helix
Crick and Watson's elucidation of the structure of DNA using model making
Using models as representations of the real world - Crick and Watson used model making to discover the structure of DNA
DNA differs from RNA in the number of strands present, the base composition and the type of pentose
Gel electrophoresis is used to separate proteins or fragments of DNA according to size.
DNA profiling involves comparison of DNA.
Tandem repeats are used in DNA profiling.
Use of DNA profiling in paternity and forensic investigations.
Analysis of examples of DNA profiles.
