PCR: Polymerase chain reaction is a method widely used in molecular biology to make multiple copies of a specific DNA segment. Using PCR, a single copy of a DNA sequence is exponentially amplified to generate thousands to millions of more copies of the particular DNA segment.

Many foods naturally contain microorganisms that are necessary for production of the food or that may bring about health benefits. However, excessive growth of contaminating microorganisms in food can cause food spoilage or illnesses arising from food infection or food poisoning. Fruits and fruit juices are particularly susceptible to contamination by yeasts and molds.

Antiseptics and antibiotics are used to control bacteria through chemical methods. Antiseptics are bacteriostatic agents (not necessarily killing them) while Antibiotics can also have bacteriostatic and bacteriocidal properties. Some bacteria and fungi produce antibiotics as their natural product. These chemicals, on the other hand, could be synthetic versions of their natural equivalents. The filter paper disc method is a simple and effective way to compare antiseptics and antibiotics based on their ability to stop bacteria from growing.
The picture depicts the relative effectiveness of an antiseptic agent (Iodine) and one antibiotic (ampicillin) against two organisms: S. epidermidis and E. coli. (Distilled water had been used as control).
The millimetre scale clearly shows the zone of inhibition from the edge of the disk to the edge of the growth.

☕️❤️ Is coffee bad for your heart? Maybe not!

According to a new American Heart Association scientific statement, up to 400 mg of caffeine per day (roughly 4–5 cups of coffee) is considered safe for most healthy adults.

Moderate coffee consumption has even been associated with a lower risk of stroke, heart failure, coronary heart disease, and type 2 diabetes.

⚠️ But remember: coffee ≠ energy drinks. And if caffeine causes palpitations, anxiety, or insomnia, your personal limit may be lower.

☕️ So yes, you can enjoy your coffee—with moderation!
