1 NUCLEIC ACIDS

2 The four major classes of macromolecules are: Carbohydrates Proteins Lipids Nucleic acids

3 There are two types of nucleic acids: __________ or deoxyribonucleic acid __________ or ribonucleic acid RNA DNA

4 Chromosomes are X-shaped structures found in the nucleus of cells.

5 DNA contains the genetic information and the instructions for making proteins. Chromosomes are composed of DNA. chromosome

6 Nucleic acids are polymers that are made up of monomers called nucleotides. nucleotide Nucleic Acid Polymer monomer

7 A nucleotide is made of three parts: A phosphate A sugar A base A NUCLEOTIDE P Base Sugar

8 Each nucleotide in DNA is composed of a _________, a ______, and a _____. A NUCLEOTIDE P Base Sugar phosphate sugar base

9 There are only four different nucleotides. These nucleotides differ in their bases. A NUCLEOTIDE P Base Sugar They differ here!

10 A NUCLEOTIDE

11 There are four different bases in DNA: Adenine --- A Thymine --- T Cytosine --- C Guanine --- G

12 P Adenine Sugar Four different nucleotides P Thymine Sugar P Cytosine Sugar P Guanine Sugar How do they differ?They differ in their bases!!!
