Deoxyribonucleic acid
-Found in nucleolus of cells (nuclear DNA) and mitochondria (mitochondrial DNA)
-1 DNA molecule = 1 chromosome
Double Helical structure
-Contains Phosphate and deoxyribose sugars
-Adenine pairs with Thymine
-Guanine pairs with Cytosine
Nucleotide
-Monomer of DNA
-Contains 1 nitrogen base, 1 Phosphate and 1 deoxyribose sugar.
Functions of DNA
-Stores hereditary information, from parent to offspring, and makes up the genes on the chromosome
-Genes (segments of DNA) control the different traits of an organism
Genetics
-Carries genes of protein synthesis
Protein and protein synthesis
DNA Replication
-Production of 2 identical DNA molecules formed from a single one. They are identical to each other and the
original DNA molecule
-Takes place in the nucleolus of the cell
-Takes place during interphase (before cell division)
