The three components that make up a nucleotide are a sugar molecule, a phosphate molecule and one of the four nitrogenous bases. These three components form the double helix shape of DNA.Know More
A nucleotide is a basic structural unit of nucleic acids, such as DNA and RNA. The sugar molecule is either ribose or deoxyribose, and the bases are adenine, cytosine, guanine and thymine. These three components fit together in a double helix shape.
Adenine and guanine are purine bases that have a double ring structure. Cytosine and thymine are pyrimidine bases that have a single ring structure. A purine base always pairs with a pyrimidine base. It follows that a thymine molecule only pairs with an adenine molecule and a guanine molecule only pairs with a cytosine molecule.
The structure of the nitrogenous bases for a nucleotide helped biologist James Watson and physicist Francis Crick determine the double helix structure, or twisted ladder shape, of DNA in 1953. The sugar and phosphate components form the two long strands of the ladder. The base pairs, adenine and thymine or cytosine and guanine, constitute the rungs of the ladder.Learn more about Molecular Biology & DNA
The basic unit of DNA is a nucleotide. Each nucleotide consists of three portions: a phosphate group, a five-carbon sugar and a nitrogenous base. DNA uses four nitrogenous bases: adenine, thymine, guanine and cytosine.Full Answer >
Fats are mainly made up of glycerides, but there are many other minor components of fats. These include phospholids, glycolipids, phosphoinositides, plant sterols like sitsterol and stigmasterol, vitamins E and A, unsaturated hydrocarbons like squalene and carotenoids are also found in fats. Fats may also contain derivatives of their natural components after they have undergone processes like oxidation, decomposition and polymerization.Full Answer >
The three components of a nucleotide are the nitrogenous base, the five-carbon sugar and the phosphate group. In turn, the nucleotides are the building components of both DNA and RNA.Full Answer >
