|
Five elements found in DNA
|
carbon
nitrogen phosphorous hydrogen oxygen |
|
|
Function of DNA
|
"hereditary code of life"; contains information that determines an organism's traits and is transmitted from one generation to another; half genes from mother and half from father
|
|
|
DNA Location
|
Nucleus of a cell
|
|
|
Where is DNA found?
|
In a living things
Ex: * Banana * Tree * Blood * Spinach * Mosquito |
|
|
How is DNA organized within the cell?
|
packed through a series of twists so that it easily fits into the cell's nucleus; double helix shape is wrapped around proteins and is coiled into a compact chromosome that's spiral shaped
|
|
|
Visible?
|
Double helix too thin to be seen w/o high tech material
Chromosomal DNA from single cell - not naked eye Chromosomal DNA from multiple cells - can be seen (mucous like) |
|
|
Length of DNA
|
length of DNA is 10,000 times as long as cell; only 10% of cell's volume
|
|
|

|
large biological molecules necessary for life
|
|
|
4 Nucleic Acids
|
Adenine
Thymine Guanine Cytosine |
|
|

|
All the genes and DNA in every cell
|
|
|

|
the assembly of a phosphate, a sugar, and a nucleic acid

Additional Information
|
More than 30,000 genes in each cell of your body
Every plant/animal has a different genome Watson and Crick won Nobel Peace Prize for their study of DNA Outside part is "backbone" |
