New cards
DNA and RNA are polynucleotides
DNA and RNA are polynucleotides
2
New cards
sugars
* DNA = deoxyribose
* RNA = ribose
3
New cards
shape
* DNA = polymer made up of two strands coiled around to make a double helix
* RNA = only made up of one polynucleotide strand, single stranded
4
New cards
bases
* DNA = adenine, thymine, guanine, cytosine
* complementary base pairing = A and T, G and C
* RNA = adenine, thymine, guanine, uracil
* contains uracil instead of thymine
5
New cards
length
* DNA is longer, RNA is shorter
