Nomenclature: Microarrays are commonly referred to by which of the following names in biotechnology and genomics?

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:

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:

Common Pitfalls:
Assuming one term implies superior technology; terms are largely contextual.

Final Answer:
All of these.
