Aim: What is the structure of the DNA molecule?
... DNA is a special molecule found in the cells which make up a chromosome. Chromosomes are found in the nucleus of a cell. (Therefore DNA is in the nucleus) There are 46 pairs of chromosomes in the human cell. DNA is an instruction manual for all the processes that the organism does. DNA has all the i ...

Mutagen
In genetics, a mutagen is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations above the natural background level. As many mutations can cause cancer, mutagens are therefore also likely to be carcinogens. Not all mutations are caused by mutagens: so-called ""spontaneous mutations"" occur due to spontaneous hydrolysis, errors in DNA replication, repair and recombination.
