Laboratory Bio-Techniques · Zoology

Which statement correctly links the techniques PCR, gel electrophoresis, and chromatography?

  1. All three are used only for protein synthesis
  2. All three require an applied electric current
  3. All are molecular analysis and separation tools
  4. All three are exclusive to developmental biology
Show answer and explanation

Correct answer: All are molecular analysis and separation tools

PCR amplifies specific DNA sequences, gel electrophoresis separates biomolecules by size and charge, and chromatography fractionates chemical mixtures by differential affinity. Together, these techniques are core analytical tools across all branches of modern molecular biology and biochemistry.
