This 12-slide Powerpoint presentation covers 'Topic 2.6 - Structure of DNA & RNA' in the 2016 IB Biology curriculum. Each slide includes the specific learning objective as well as key vocabulary that students should note.
The presentation itself contains minimal information as it is intended to be used with teacher guidance. They are also formatted to be visually pleasing and to print well for handouts or revision. Please see the preview file for an idea of the slide aesthetic and level of detail.
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!
U1: The nucleic acids DNA and RNA are polymers of nucleotides.
U2: DNA differs from RNA in the number of strands present, the base composition and the type of pentose.
U3: DNA is a double helix made of two antiparallel strands of nucleotides linked by hydrogen bonding between complementary base pairs.
A1: Crick and Watson’s elucidation of the structure of DNA using model making.
S1: Drawing simple diagrams of the structure of single nucleotides of DNA and RNA, using circles, pentagons and rectangles to represent phosphates, pentoses and bases.
