DNA is a long molecule composed of two chains of smaller molecules called nucleotides, each which contain a region of nitrogen called the nitrogenous base, a carbon-based sugar molecule called deoxyribose and a region of phosphorus called the phosphate group. There are four types of nitrogenous base
A double helix, or a twisted-ladder shape, is the standard structure of DNA. It consists of two strands of a sugar-phosphate backbone and the nucleotide base pairs adenine, thymine, guanine and cytosine. Adenine pairs with thymine, and guanine pairs with cytosine by non-covalent hydrogen bonds.
The structure of DNA was discovered by James Watson and Francis Crick. They published their paper "A Structure for Deoxyribose Nucleic Acid" in April of 1953. In 1962, they won the Nobel Prize in Physiology or Medicine for their discovery of the double helix structure of DNA.
The backbone of the DNA molecule is made of a repeated pattern containing a sugar called deoxyribose and a phosphate group. The backbone is spatially arranged in the form of a double helix, with base pairs connecting the two sugar-phosphate strands.
DNA, or deoxyribonucleic acid, is used in the human body in order for an organism to reproduce, develop and survive as well as in science for genetic engineering, forensics, bioinformatics, evolutionary history and information storage. A human's DNA code contains about 3 billion bases and 20,000 gen
The majority of DNA is located in the cell nucleus, where it is called nuclear DNA. A small amount is located in the mitochondria, where it is called mitochondrial DNA.
DNA is made of repeating units called nucleotides. The four nucleotides in DNA are adenine, cytosine, guanine and thymine. Adenine binds with thymine, and guanine binds with cytosine.
The phrase that best describes the structure of DNA is "double helix." The DNA molecule resembles a ladder that has been twisted. This double-helical structure was first proposed by researchers James Watson and Francis Crick.
DNA, or deoxyribonucleic acid, is a chain that is made up of smaller parts known as nucleotides. These nucleotides are then made up of three different parts of nucleotides: the sugar group, the phosphate group and a group of four different nitrogen bases, which are adenine (A), cytosine (C), guanine
DNA works by storing information that tells the body how to develop, survive and reproduce cells. DNA sequences are made up of four types of nucleotides: adenine, thymine, cytosine and guanine. Information in DNA is stored by the ordering of bonded nucleotides and resides in pieces of DNA called gen
