DNA together with RNA are the most important molecules in biology. It is the hereditary material in humans and almost all other organisms in our planet. Most DNA is found in the nucleus and some or small portion can be found in the mitochondria.
The main features of the three-dimentional structure of DNA are:
DNA is double-stranded composing of two polynucleotide strands alongside each other which are wound round each other to form a double helix. The two strands are joined together by hydrogen bonds between the bases and these bases form base pairs which is like a rung of a ladder. The base pairs are specific. Base pair A only binds to T (T with A), and C only binds to G (G with C). These are called complementary base pairs. As a wholes, DNA molecules control the production of proteins which characterize each type of organism.

One difference between cancer cells and normal cells is that cancer cells continue to divide even when they are tightly packed together (option C).
<h3>What are cancer cells?</h3>
Cancer is a disease in which the cells of a tissue undergo uncontrolled (and often rapid) proliferation.
When normal cells become cancerous, they lose the ability to regulate cell division, hence, they continue to divide excessively.
Normal cells are characterized by their ability to regulate cell division during the cell cycle.
Therefore, one difference between cancer cells and normal cells is that cancer cells continue to divide even when they are tightly packed together.
