Pressure Pressure is the force acting on a unit area of a surface. P = F / A Where, P is Pressure (Pa) F is Perpendicular Force applied (N) A is Area (m²) Units : Pascal (Pa), Newton per square metre (N/m²) Relationship between units : 1 Pa = 1 Nm⁻² Figure 1.

What Is PCR? Imagine you find a single strand of hair at a crime scene. Inside that hair is a tiny, tiny amount of DNA that is barely enough to test. How do scientists work with something so small? The answer is PCR, Polymerase Chain Reaction. It's a technique that copies a specific segment of DNA millions (or even billions) of times, so there's enough to analyze. Think of PCR as a DNA photocopier PCR is fast, precise, and incredibly powerful. The Big Idea PCR takes a tiny p
