Techniques in Molecular Biology

Tools of the Trade

Modern biology relies on powerful techniques to study genes, proteins, and cells.

DNA Manipulation

  • PCR (Polymerase Chain Reaction): Amplifies small DNA samples.
  • Gel Electrophoresis: Separates DNA based on size.

Protein Analysis

  • Western Blotting: Detects specific proteins.
  • ELISA: Measures protein concentration.

Imaging and Sequencing

  • Microscopy: Visualizes cells and organelles.
  • DNA Sequencing: Reads the order of DNA bases.

Why These Matter

These tools are essential for research, diagnosing diseases, and developing new therapies.

Examples

  • PCR is used in forensic labs to match crime scene DNA.

  • COVID-19 tests often use RT-PCR to detect viral RNA.

In a Nutshell

Molecular biology techniques allow us to analyze and manipulate DNA, proteins, and cells.
