DNA+3+&+4

- The new DNA molecules are exactly the same as the old one
- Cell divides so organism can reproduce and DNA replicates because every cell needs a copy of the DNA instructions when the cell divides - Replicates right before when a cell divides

__**Vocabs**__
DNA Replication- The process where DNA copy itself Cell division- Process when a cell divides in to two or more cells that are the same Traits- Characteristics that are passed through its genes, traits are the same when the DNA molecule is replicated Nucleic Acids- Building blocks of living organisms (DNA is a type of nucleic acid), made up of **uracil**, **guanine**, **cytosine**, **thymine**, **adenine**


 * Adenine pairs with thymine **


 * Guanine pairs with cytosine **

-Found in the chromosomes which are in the nucleus
 * Where are genes found? **

=** What are Genes? **= **- Segments of DNA** **- Carry your traits and pass them on to offsprings** **- Made up of DNAs** **- Contains codes for protein which are codes for traits** **-**
