Question

The instrument that automates the rapid and precise temperature changes required to copy a DNA strand is:

• A. Centrifuge
• B. Thermal cycler
• C. Incubator
• D. Vortex

Hint:

Thermal cyclers are essential for efficient and accurate DNA amplification in molecular biology.

Answer 1

The Correct Option is B

The thermal cycler, or PCR machine, is a device that cycles through the precise temperatures needed for DNA amplification. It is indispensable in molecular biology for processes like DNA replication, sequencing, and forensic analyses.
