Describe a DNA molecule as two strands coiled to form a double helix, the strands being linked by a series of paired bases: adenine (A) with thvmine (T) and cvtosine (C) with guanin (G)
If we look at a section of the double helix we will see bases that are close together and there are four different types of bases: adenine (A) with thvmine (T) and cvtosine (C) with guanin (G).
In the molecule, these bases are holding together the two helixes and are held together by pairing between A with T on one side and C with G on the other. These are known as the base pairs.
If we look on one side, we can see the order is ACTGAACCAG. This is the order of the bases and this is called the gene.
Gene can be defined as the order of the bases and the number of the bases. This is for the construction of the protein in the cytoplasm and this gives us the characteristic.
