- Q1
DNA is a single helix structure
falsetrueTrue or False30s - Q2
This scientist's work on X-Ray Crystallography resulted in Watson and Crick being able to calculate the structure of DNA as a double helix.

What type of sugar is found in DNA nucleotides?
ribose
deoxyribose
fructose
glucose
30s - Q4
Which nitrogen base is not found in DNA
adenine
uracil
thymine
cytosine
30s - Q5
Thanks to Chargaff's Rules, Watson and Crick were able to figure out how base pairing works in DNA. For example, if 20% a DNA molecule contains Adenine, then what amount of Guanine would it contain
