- complex material that determines all the characteristics of an organism
Phenotype

Four bases that make up the DNA
A - Adenine
G - Guanine
C - Cytosine
T - Thymine
Complementary Base Pairing consists of…
Adenine is paired with Thymine (A-T)
Cytosine is paired with Guanine (G-C)
Number of chromosomes within the human body
46 chromosomes
Sperm and egg cells contain…
23 chromosomes (or one of each pair)
Genes
- determine the characteristic of an organism
- each chromosome can carry a thousand genes

- isolating a number of cells and photographing the chromosomes contained in the cells
- it is then cut up so that the individual chromosomes can be arranged into homologous paris according to their size.
