WHAT IS ELECTRO MAGNETIC INDUCTION
DNA is a double helix. For a picture of what that means, see

Electrical induction produces an EMF (voltage) in a circuit when the magnetic field through the circuit changes.

The structure of DNA, which stands for deoxyribonucleic acid, is a double helix, meaning it is made up of two strands that are wound around each other in a twisted ladder or staircase shape.
To understand the structure of DNA, it is important to know its components. DNA is composed of molecules called nucleotides, which consist of three main parts: a sugar molecule called deoxyribose, a phosphate group, and a nitrogenous base. There are four different nitrogenous bases in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G).
The two strands of DNA are held together by hydrogen bonds between the nitrogenous bases. Adenine (A) always pairs with thymine (T), forming two hydrogen bonds, while cytosine (C) always pairs with guanine (G), forming three hydrogen bonds. This complementary base pairing is known as Chargaff's rules.
The twisted ladder shape of DNA is formed by the two strands wrapping around each other in a helical structure. The sugar and phosphate groups make up the sides, also known as the backbone, of the ladder, while the pairs of nitrogenous bases make the rungs.
Understanding the structure of DNA is crucial because it carries and transmits genetic information. The sequence of nucleotides in DNA provides the instructions for building and maintaining an organism, making it an essential molecule for life.
