1
DNA DNA→RNA→Protein
2
Nucleotides Nucleotides are the pieces of DNA (monomer)
Each nucleotide has: A backbone of a 5 Carbon Sugar (Deoxyribose) and a phosphate Nitrogen bases: Adenine, Guanine, Cytosine, Thymine
3
Double Helix These nucleotides come together by base pairing with the nitrogen bases Adenine to Thymine with a hydrogen bond Guanine to Cytosine with a hydrogen bond
5
DNA’s Function Holds the genetic information of the organism, that allows the Ribosomes to make protein specifically for that organism. ½ from mom, ½ from dad.
7
What about mRNA? RNA is a disposable copy of DNA used to make proteins
Why is it called RNA and not DNA? It has a different sugar called Ribose instead of Deoxyribose
8
Differences in DNA & mRNA
1- sugar is ribose not deoxyribose 2- RNA is single-stranded 3- RNA has a nitrogen base of Uracil not Thymine. What would Uracil bond to then?
9
So What? Why do we care about base pairs?
Well, for every 3 bases it codes for a certain protein to be made.
