DNA Chapter 12.1/12.2

DNA = deoxyribose nucleic acid What is DNA? DNA = deoxyribose nucleic acid

What is DNA? DNA is made up of nucleotides. Nucleotides: 5 – carbon sugar (deoxyribose) Phosphate group Nitrogenous base Adenine – Guanine Thymine – Cytosine

Double Helix DNA is a double helix.  Twisted ladder

Base Pairings Adenine – Guanine Thymine – Cytosine They’re held together by hydrogen bonds Hydrogen bonds are WEAK Why would having weak bonds be good for DNA? These are base pairings!

DNA and Chromosomes What does DNA look like in prokaryotic cells? What does DNA look in eukaryotic cells?

Chromosomes vs. Chromatin DNA wrapped around a protein Found in the nucleus Chromosomes: DNA coiled tightly Shaped liked an “X” Found in the nucleus

THINK! What does replicate mean? Does DNA replicate?? If it does, why is that important??

DNA Replication DNA separates into two strands Replication fork DNA “unzips” when it separates

DNA Replication After DNA separates, new base pairs are added. AGGTCTA What would the new base pairs be??

How DNA Replicates DNA polymerase = the enzyme in charge of adding new bases to unzipped DNA.
