Definition
- Noun:
- The molecule that carries genetic information in all living organisms: Deoxyribonucleic acid (DNA) is a long, complex molecule found in the nucleus of cells, composed of nucleotides arranged in a double helix structure. It contains the instructions needed for an organism to develop, survive, and reproduce.
Examples of Usage
- Noun:
- Scientists extracted deoxyribonucleic acid from the ancient bone sample.
- The sequence of deoxyribonucleic acid determines an individual's inherited traits.
Advanced Usage
- "To sequence deoxyribonucleic acid": to determine the precise order of nucleotides within a DNA molecule.
- The project aims to sequence the deoxyribonucleic acid of the entire population.
- "Deoxyribonucleic acid evidence": forensic material derived from DNA analysis.
- Deoxyribonucleic acid evidence was crucial in solving the cold case.
