Is DNA a molecule or a compound?
DNA, short for deoxyribonucleic acid, is the molecule that contains the genetic code of organisms. This includes animals, plants, protists, archaea and bacteria. It is made up of two polynucleotide chains in a double helix. [1] DNA is in each cell in the organism and tells cells what proteins to make.
The DNA structure defines the basic genetic makeup of our body. In fact, it defines the genetic makeup of nearly all life on earth. Table of Contents. What is DNA? Discovery; Diagram; DNA Structure; Chargaff’s Rule; DNA Replication; Function of DNA; Why DNA is called a Polynucleotide Molecule?

DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes.

- why DNA has 3 phosphates and when it loses them why it looses 2 phosphates instead of 1?Are you asking about why the nucleotides (nucleoside triphosphates) lose two phosphates when they are incorporated into a nucleic acid like DNA? If...
Your genome is the complete set of instructions your body needs to function. It’s made of a long molecule called deoxyribonucleic acid, or DNA for short. DNA is made up of four building blocks, or bases. These are called adenine, cytosine, guanine and thymine – usually shortened to A, C, G and T.
Deoxyribonucleic acid (DNA) is a molecule that encodes an organism's genetic blueprint. In other words, DNA contains all of the information required to build and maintain an...
Sep 13, 2023 · DNA stands for Deoxyribonucleic acid, a macromolecule that carries genetic information in all living organisms, from the tiniest microorganisms to the most complex multicellular humans. DNA is a fundamental molecule that holds life’s blueprint.
Jan 19, 2019 · DNA Definition: Shape, Replication, and Mutation. DNA (deoxyribonucleic acid) is a type of macromolecule known as a nucleic acid. It is shaped like a twisted double helix and is composed of long strands of alternating sugars and phosphate groups, along with nitrogenous bases (adenine, thymine, guanine, and cytosine).
