DNA Structures
DNA (Deoxyribonucleic Acids) Store and transmit genetic information. It is made from a String of Nucleotides.
The Pentagon shape is a five carbon sugar which is deoxyribose. There is a phosphate group which are the circles off to the sides. Lastly there is a nitrogen base ( Adenine, Thymine, Guanine, and Cytosine).
Adenine is always paired with Thymine
Guanine is always paired with Cytosine
Both of these bases are connected by hydrogen bonds.
There is a sugar/ Phosphate backbone which make up the outside of the DNA molecule.
Purines and Pyrimidines
Adenine and Guanine are the Purines. The pyrimidines are Thymine and Cytosine.

James Watson and Franklin Crick are the men who discovered the double helix.Some people who had some Important discoveries are:
Another very important person is Rosalind Franklin who devoted her life to finding out as much as she could about DNA structures using x-rays. Her work eventually led to the double helix.
Adenine pairs with Thymine***Remember: Erwin Chargaff's Base-Pairing Rules:
Cytosine pairs with Guanine
These bases pair together because they are similar in chemical composition.%A = %T
%C = %G
A pairs with t
ReplyDeletec pairs with g

ReplyDeleteDNA are strings of nucleotides.
ReplyDeleteNucleotides are made up of three basic components:
1. A five- carbon sugar called deoxyribose.
2. A phosphate group.
3. A nitrogen base (A, T, C, or G)
