1. a short chain of nucleotides (typically 2–20 units) linked together, used in molecular biology and genetics research.
Usage: technical term used in biochemistry and molecular biology; commonly abbreviated as 'oligo'

Examples

• Scientists designed an oligonucleotide probe to detect specific DNA sequences.
• The oligonucleotide was synthesized in the laboratory for use in genetic testing.
• Antisense oligonucleotides can block the expression of disease-causing genes.
• The researcher used fluorescently labeled oligonucleotides to identify target molecules.
• Short oligonucleotides are easier to synthesize than long DNA strands.
• Oligonucleotide therapy has emerged as a promising treatment for certain genetic disorders.
