NITROGENOUS BASES
Nitrogenous bases are typically classified as the derivative sof 2 parent compounds pyrimidine and purine
bonts A and T that forms a double bond
bond C and G that forms a triple bond.

PYRIMIDINE
Pyrimidine .
Pyrimidine is made of 2 nitrogen atoms in the ring nitrogen at positions 1 and 3
In DNA and RNA these bases form hydrogen bonds with their complementary purines.
CYTOSINE & Thymine

PURINE
Purine is a heterocyclic aromatic organic compound
Purine is the most widely occuing nitrogen-containing herterocyle in nature.

DNA Extraction
STEPS TO AN EXTRACTION
1) Collecting DNA
* When you collect DNA from the check you would ask them to since with salt water so that you have will get more cells on the swab.
2) Burst cells open to get to the DNA
* You want to get to the inside of the cell. You get into the cell by putting an extraction solution on the cell to open it and allow DNA to be released from the chromosome.
3) Separate DNA and purify
*You separate DNA by putting concentrated salt solution to the tube. This causes the DNA to rise in between the solution and the other partaking organisms in a cell. The DNA will be in a clump like cluster.
4) Isolate concentrated DNA
*Then you can take the DNA out and place it in another tube and keep the DNA.
Each step is very precise and important!!!!!!
