8. DNA Structure DNA consists of two molecules that are arranged into a ladder-like structure called a Double Helix. A molecule of DNA is made up of millions of tiny subunits called Nucleotides. Each nucleotide consists of: 1. Phosphate group 2. Pentose sugar 3. Nitrogenous base

9. Nucleotides Phosphate Pentose Sugar Nitrogenous Base

10. Nucleotides The phosphate and sugar form the backbone of the DNA molecule, whereas the bases form the “rungs”. There are four types of nitrogenous bases.

11. DNA Structure Because of this complementary base pairing, the order of the bases in one strand determines the order of the bases in the other strand.

12. Nucleotides Each base will only bond with one other specific base. Adenine (A) Thymine (T) Cytosine (C) Guanine (G) Form a base pair. P urines Form a base pair. Pyrimidines

13. Nucleotides A Adenine T Thymine G Guanine C Cytosine

14. G G A T T A A C T G C A T C

15. DNA Structure To crack the genetic code found in DNA we need to look at the sequence of bases. The bases are arranged in triplets called codons. A G G - C T C - A A G - T C C - T A G T C C - G A G - T T C - A G G - A T C

16. A gene is a section of DNA that codes for a protein. Each unique gene has a unique sequence of bases. This unique sequence of bases will code for the production of a unique protein. It is these proteins and combination of proteins that give us a unique phenotype.

17. DNA Replication Is the process by which a DNA molecule is duplicated into identical DNA molecules. It occurs in the nucleus of the cell STEPS IN REPLICATION During replication, the DNA ladder separates, or unzips Free nitrogen bases “float” in the nucleus pair up with the nitrogen bases on each half of the DNA Two new DNA molecules are formed
