,→About DNA
: [[DNA]] is found in the [[nucleus]] of [[Eukaryotic Cell|eukaryote]]s and floating freely in the [[cytoplasm]] of [[Prokaryotic Cell|prokaryote]]s.
: [[DNA]] in [[eukarytotic Cell|eukaryotes]] coils together to make [[chromosomes]].
: [[DNA]] is passed from parent to [[offspring]].: [[DNA]] is made of arranged in [[gene]]s that control most of our physical appearance.: [[DNA]] determines your eye colour, nose shape, height, skin colour and whether you are [[male]] or [[female]]. All of these things can be affected by environment as well, but the [[DNA]] provides the original instructions on how to build you.
: [[DNA]] has a '''double helix''' structure, which means it is shaped like twisted ladder.
: [[DNA]] is made from three [[Nucleotide|nucleotide bases]] called [[Adenine]], [[Thymine]], [[Cytosine]], and [[Guanine]] referred to as A, T, C and G.
: The [[nucleotide]]s are arranged in complementary pairs. [[Adenine]] and [[Thymine]] pair up on opposite sides of the [[DNA]] strand. The same is true for [[Cytosine]] and [[Guanine]]. When the strand is pulled into two pieces this allows the [[DNA]] to make two exact copies of itself.
