Generally, a phosphate group, a deoxiribose sugar and a nitrogenous base.
nucleotides.
A nucleic acid is a biological polymer (a chain composed of links) made of building blocks (the links) called nucleic acids. The most common nucleic acids are DNA and RNA.
Protein and nucleic acid.
nucleic acid
Yes. All viruses are composed of a nucleic acid surrounded by a protein capsid. When the capsid is not present, the the infectious nucleic acid is called viroid. When the nucleic acid is not present, the infectious protein coating is called prion.
There is none. DNA is a nucleic acid composed of nucleotides. There are no amino acids in DNA.
virus
The composition of the nucleic acid-DNA includes polynucleotides which are composed of guanine, adenine, thymine, cytosine, a phosphate group, and deoxyribose (a monosaccharide sugar).
A nucleotide is not classified as a carbohydrate. A nucleotide is a building block of DNA and RNA, which are nucleic acids. Carbohydrates are nutrients that typically are composed of carbon, hydrogen, and oxygen.
nucleic acids
It is a nucleic acid (and specifically, deoxyribose nucleic acid).
An alien nucleic acid is an acid composed of bases other than adenine, guanine, thymine, uracil and cytosine and/or sugars other than ribose and deoxyribose - thought to be a clue as to the possibility of extraterrestrial life.
