An organic acid and polymer composed of four nitrogenous bases--adenine, thymine, cytosine, and guanine linked via intervening units of phosphate and the pentose sugar deoxyribose.

DNA is an acid because of the phosphate groups between each deoxyribose. This is the primary reason why DNA has a negative charge.

Nucleoside In molecular biology; a molecule composed of a sugar (2' deoxyribose in DNA; ribose in RNA) which is linked to a purine (adenine or guanine) or a pyrimidine (thymine (DNA), cytidine or uridine (RNA)).
Full article >>>

Each nucleotide sub-unit consists of a phosphate, deoxyribose sugar and one of the 4 nitrogenous nucleotide bases grouped into 2 categories, purine and pyrimidine.

Nuclease
An enzyme which cleaves phosphate-deoxyribose bonds within (endonuclease) or at the end (exonuclease) of a nucleotide sequence. Nucleases usually recognize a specific substrate, such as single- or double-stranded DNA or RNA.
Full article >>>

A single-stranded nucleic acid similar to DNA but having ribose sugar rather than deoxyribose sugar and uracil rather than thymine as one of the pyrimidine bases.
Also known as: ribonucleic acid ...

Pentose sugar: A sugar molecule containing five carbon atoms. E.g.: deoxyribose.
Phage: A virus which infects a bacterial cell. Also called a Bacteriophage.
Full article >>>

A subunit of DNA or RNA consisting of a nitrogenous base (purine in adenine and guanine, pyrimidine in thymine, or cytosine for DNA and uracil cytosine for RNA), a phosphate molecule, and a sugar molecule (deoxyribose in DNA and ribose in RNA).
Full article >>>

DNA is composed of two chains of nucleotides linked together in a ladder-like arrangement with the sides composed of alternating deoxyribose sugar and phosphate groups and the rungs being the nitrogenous bases as indicated by the diagram below.

nucleosides - compound composed of a purine or pydimidine base linked to either a ribose or deoxyribose sugar. DNA and RNA are not polymers of nucleosides.

Nucleoside: A term refering to the combination of adenine, cytosine, guanine, or thymine with a ribose or 2-deoxyribose sugar moiety. A nucleoside is not phosphorylated.
