A Level Biology Revision quotThe Structure of DNA and RNAquot

>> YOUR LINK HERE: ___ http://youtube.com/watch?v=HRga77i64nY

You can find all my A Level Biology videos fully indexed at https://www.freesciencelessons.co.uk/... • In this video, I take you through the structure of DNA. We explore what is meant by complementary base pairing and why the DNA polynucleotides are antiparallel. I then show you how to calculate the proportions of the different nucleotides in DNA. Finally, we look at the structure of RNA and the key differences between RNA and DNA. • This video is aimed at the UK A Level Biology specifications. Students studying International A Level Biology will need to check their specification.
