what are the components of dna?
442436
DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.

All of the information needed to build and maintain an organism — whether it's a human, a dog, or a bacterial cell — is contained in its DNA. DNA molecules are composed of four nucleotides, and these nucleotides are linked together much like the words in a sentence.

A nucleic acid is an organic compound, such as DNA or RNA, that is built of small units called nucleotides. Many nucleotides bind together to form a chain called a polynucleotide. The nucleic acid DNA (deoxyribonucleic acid) consists of two polynucleotide chains.

['a nitrogenous base - organic molecules containing carbon and nitrogen. ... ', 'a pentose (five-carbon) sugar -In a DNA, it is called deoxyribose while in RNA it is ribose.']

DNA is made up of four nucleotides — the building blocks of nucleic acids — which are composed of a nitrogenous base, a five-carbon sugar (ribose or deoxyribose), and at least one phosphate group. Adenine (A), Thymine (T), Guanine (G), and Cytosine (C) are called nucleotides.

All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information. It is often compared to a blueprint, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules.
454669
DNA is constructed of two strands, consisting of sugar molecules and phosphate groups. Between these two strands are nitrogen bases, the compounds which make up organisms' genes, with hydrogen bonds between them. Those hydrogen bonds have sometimes been seen as crucial to holding the two strands together.

['FIRST PART. CELLS CONTAIN DNA THAT IS PASSED CELL TO CELL DURING CELL DIVISION.', 'SECOND PART. CELLS ARE SIMILAR IN CHEMICAL COMPOSITION AND REACTIONS THAT MAINTAIN HOMEOSTASIS.', 'THIRD PART. ALL BASIC CHEMICAL AND PHYSIOLOGICAL FUNCTIONS ARE CARRIED OUT INSIDE THE CELL.', 'FOURTH PART.']
127342
Each nucleotide is made up of three components: a nitrogenous base, a pentose (five-carbon) sugar called ribose, and a phosphate group. Each nitrogenous base in a nucleotide is attached to a sugar molecule, which is attached to one or more phosphate groups.
764735
There are four basic components required to initiate and propagate DNA synthesis. They are: substrates, template, primer and enzymes.
1307683
The backbone of DNA consists of a phosphate group and a deoxyribose. These two components are therefore connected by a phosphodiester bond. The nucleotides are not included in the backbone.
22290
DNA contains four basic building blocks or 'bases?': adenine? (A), cytosine? (C), guanine? (G) and thymine? (T).

DNA is contained in blood, semen, skin cells, tissue, organs, muscle, brain cells, bone, teeth, hair, saliva, mucus, perspiration, fingernails, urine, feces, etc.
867008
A nucleotide is the basic building block of nucleic acids. RNA and DNA are polymers made of long chains of nucleotides. A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.
280738
A nucleotide is an organic molecule that is the building block of DNA and RNA. ... A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.
1173373
DNA and RNA are made up of monomers known as nucleotides. The nucleotides combine with each other to form a polynucleotide: DNA or RNA. Each nucleotide is made up of three components: a nitrogenous base.
1101763
DNA is made up of six smaller molecules -- a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine).
