Nomenclature: Microarrays are commonly referred to by which of the following names in biotechnology and genomics?
-
ABiochips
-
BDNA chips
-
CGene chips
-
DAll of these
-
EProtein pads only (exclusive term)
Answer
Correct Answer: All of these
Explanation
Introduction / Context:Microarrays place thousands of probes on small substrates for simultaneous analysis. Over time, several synonymous terms have emerged in industry and academia to describe these platforms.
Given Data / Assumptions:
- “Biochip” is a broad term for biological microdevices on chips.
- “DNA chip” or “gene chip” specifically refer to nucleic acid microarrays.
- Usage varies by community and application focus.
Concept / Approach:Because the underlying concept is the same—many probes on a chip addressed in parallel—these terms are often used interchangeably, with context (DNA, protein, glycan) clarifying the probe type.
Step-by-Step Solution:
Identify common synonyms used in literature and product names.Recognize that all three terms correctly describe microarray devices.Select the inclusive option “All of these.”Verification / Alternative check:Major vendors and papers regularly use these terms; “gene chip” is even a registered tradename historically associated with DNA arrays.
Why Other Options Are Wrong:
Protein pads only: too narrow and not a standardized exclusive term for all arrays.Common Pitfalls:Assuming one term implies superior technology; terms are largely contextual.
Final Answer:All of these.
