2 What is a nucleic acid?The last type of macromolecules is a special group called nucleic acids.These very large organic compounds are found in all living cells. The two types of nucleic acids are DNA and RNA.
3 What are the building blocks of nucleic acids? The building blocks of nucleic acids are nucleotides. Nucleotides haveA sugarA phosphateA nitrogen base (there are 5 different bases)
4 Structure of Nucleic Acids The shape of nuclei acids isvery distinctive.A helix is like a spiral.
5 Structure of Nucleic Acids DNA is a double helix similar to aspiral staircase
6 Structure of Nucleic Acids while RNA is a single strand.
7 What are the functions of nucleic acids? These special macromolecules play very important roles in living organisms.DNA carries the hereditary traits of an organism.RNA helps cells make proteins based on the code found in the DNA
8 The DNA Molecule DNA stands for Deoxyribonucleic acid There are 4 different nitrogen bases in DNAAdenine (A)Thymine (T)Cytosine (C)Guanine (G)
9 The DNA Molecule The nitrogen bases pair up in a specific way Adenine pairs with Thymine (A-T or T-A)Cytosine pairs with Guanine (C-G or G-C)We call these bases that match up with each other complementary
10 The DNA MoleculeOn the back of your notes page write down 9 DNA bases down the left side of your paper: A-, T-, G-, G-, T- etc.You may list them in any order you chooseNow go back and write in the complementary base that matches each of your 9 bases
11 The DNA MoleculeCompare your DNA molecule with the person sitting next to youNow compare your 2 DNA molecules with the students sitting closest to youDid anyone create the same DNA Molecule?Why do you think this is the case?
