objective 3.16. describe a DNA molecule as 2 strands coiled to form a double helix. the strands being linked by a series of paired bases adenine (a) with thymine (t) and cytosine (c) with guanine (g)
one chromosome is likely to contain thousands of genes
on the gene loci expand it and you will find a double helix. the helix appear to be parallel
zoom in and the 2 helix are known as the 'sugar phosphate backbone'
inbetween/centered between these you will find a group of molecules called bases
there are 4 different bases known. adenine, thymine, cytosine and guanine.
in a molecule the bases are holding together th 3 helixes. they are held together by pairing between a+t and c+g. these are known as base pairs.
they are always found in dna holding each sides together.
an example on oneside of a double helix an order could be a,c,t,g,a,a,c,c,a,g. this is 'order of the bases.
this order is called the gene. the gene is inside the nucleus.

gene- order of the bases (a,t,c,g) on one side of double helix and number of base.
this is the code for construction of protein in cytoplasm. this gives a characteristic
