Question

What is a base in DNA?

Answer 1

DNA, or deoxyribonucleic acid, is a molecule made up of two polynucleotide chains that coil around each other to create a double helix and carry genetic instructions for all known creatures and many viruses development, function, growth, and reproduction. Nucleic acid includes Deoxyribonucleic Acid (DNA) and Ribonucleic Acid (RNA). One of the four major types of macromolecules that are required for all known forms of life is the nucleic acid, alongside proteins, lipids, and complex carbohydrates.

Complete answer:
The hereditary substance in humans and almost all other animals is DNA, or deoxyribonucleic acid. In a person’s body, the DNA of nearly every cell is identical. The majority of DNA is contained in the cell nucleus (also known as nuclear DNA), although a tiny quantity is also present in the mitochondria. The molecules that make up DNA are nucleotides. In a nucleotide, there is a phosphate group, a sugar group, and a nitrogen base.
Adenine (A), guanine (G), cytosine (C), and thymine (T) are the four chemical bases that make up DNA’s information in which it is stored as a code. The information accessible for developing and maintaining an organism is determined by the order, or sequence, of these bases.
Base pairs are formed when two DNA bases, A and T, or C and G, couple up to form a unit. Each base has a sugar molecule and a phosphate molecule connected to it. A nitrogen base, sugar, and a phosphate group make up the nucleotide. Nucleotides are arranged in a spiral known as a double helix, which is made up of two long strands.

Note:
The biological information is stored on both strands of double-stranded DNA. When the two strands separate, this information is reproduced. A considerable portion of DNA is non-coding, which means it does not act as a template for protein sequences. Since the two strands of DNA run in opposite directions, they are antiparallel. Each sugar has one of four types of nucleobases attached to it (or bases).
