a linear sequence of nucleotides as occurs in RNA and DNA.
Linear sequences of nucleotides, in which the 5' linked phosphate on one sugar group is covalently linked to the 3' position on the adjacent sugars.
A nucleic acid longer than about 20 nucelotides.
Also known as a nucleic acid. One of the four main classes of macromolecules ( proteins, nucleic acids, carbohydrates, lipids) found in living systems. Polynucleotides—long chains composed of nucleotide—form backbone of DNA, in which two polynucleotide chains interact as their nitrogenous bases connect to form what is known as the DNA double helix.
A single-stranded DNA or RNA molecule.
A linear series of connected nucleotides occurring in DNA or RNA.
A polymer of nucleotides. The nucleotide units are linked by phosphodiester bonds spanning between the sugar moieties.
A polynucleotide an organic polymer (many similar molecules chemically bonded to form a chain), of paramount significance in biochemistry. The basic unit is of a polynucleotide is the nucleotide, either DNA (deoxyribonucleic acid) or RNA (ribonucleic acid). The prefix poly comes from the ancient Greek πολυς (polys, many).
