When the dna ladder twists the way it normally does the shape of the molecule is called a double helix. The DNA is made of nucleotides consisting of a de-oxyribo sugar, a phosphate group and one of the four nitrogen base.
Adenine pairs with Thymine with 2 hydrogen bond and Guanine pairs with Cytosine with 3 hydrogen bond .This provided the clue the DNA molecule is a double helix , shaped like a twisted ladder.

<em>The main idea of Malthus' article as described above is analogous to the concept of population and carrying capacity.</em>
Explanation:
Carrying capacity can be described as the number of species of a population that a particular habitat can hold.
