Definition

Noun: - A microchip that holds DNA probes that form half of the DNA double helix and can recognize DNA from samples being tested. It is a technology used to analyze gene expression or detect genetic variations by allowing many DNA sequences to be tested simultaneously on a single small surface.

Usage

• The term "DNA chip" is used primarily in scientific, medical, and biotechnological contexts to refer to a specific tool for genetic analysis.
• It functions as a singular, countable noun (e.g., , ).

Examples

• The laboratory used a DNA chip to screen for mutations in the patient's genome.
• Researchers analyzed the gene expression profiles using a custom DNA chip.
• The development of the DNA chip has revolutionized genetic testing.

Advanced Usage

• "To hybridize to a DNA chip": This describes the process where sample DNA binds to the complementary probes on the chip.
  • The fluorescently labeled sample was allowed to hybridize to the DNA chip overnight.
• "DNA chip data": Refers to the information or results obtained from an experiment using this technology.
  • The analysis of the DNA chip data revealed new patterns of gene activity.

Variants and Related Words

• Microarray (n): A more general term for a lab tool used to detect the expression of many genes at once. A DNA chip is a specific type of microarray.
  • Gene expression microarrays are commonly used in research.
• Gene chip (n): A synonym often used interchangeably with "DNA chip."
  • The Affymetrix GeneChip® is a well-known commercial platform.

Synonyms

• Gene chip: A chip designed for genetic analysis.
• DNA microarray: A broader technical term for a high-throughput technology used to measure the expression levels of many genes simultaneously.

Related Phrases

• "To run a sample on a DNA chip": To perform an analysis using this technology.
  • We will run the tumor sample on a DNA chip to identify potential biomarkers.
• "DNA chip technology": Refers to the field or methodology involving these devices.
  • Advances in DNA chip technology have made personalized medicine more feasible.
