1 Spot the odd one out (and say why) UracilThymineCytosine RiboseDeoxyriboseThymine CytosineGuanineThymine Semi- conservative DispersiveConservative

2 What is the difference between deoxyribose and ribose? What type of spiral is DNA? How many bases are there to each turn of the DNA molecule? What three forms of evidence were used to derive the structure of DNA? How many nucleotides (on average) does it take to make a human chromosome set? What are chromosomes made of as well as DNA?

3 DNA Replication

4 Meselson and Stahl Grew microbes in 15 N growth medium Then repeatedly on 14 N growth medium DNA was extracted and separated by centrifugation
