We know DNA. But what is RNA?

We have all heard of DNA. But what exactly is RNA? RNA is similar to DNA in many ways at the structural level however; the differences that are present make RNA chemistry very different than that of DNA. We know DNA. But what is RNA? Almost everyone has heard of DNA and knows the role it plays in heredity. But another extremely important nucleic acid in the cell is RNA. RNA or Ribonucleic acid is similar to DNA in many ways at the structural level. However there are certain differences that are present in RNA chemistry that make it very different than DNA. What is RNA? RNA serves many functions in a cell and is typically a linear polymer that consists of a sugar-phosphate backbone with nitrogenous bases projecting off the backbone. This structure is very similar to DNA. Both of these nucleic acids carry genetic information, which is based on the order of the bases that are present along the chain of the molecule. The presence of a single atomic change in the...

Why do we smell when we sweat?

Why do we smell when we sweat? Sweating can be quite annoying especially since it tends to leave a big wet patch either on your back or under your arms. It makes it especially worse when your sweat tends to smell really foul. Although the bad news is that there is no way to prevent it, the good news is that you can at least tackle it. Why do we sweat? Sweating or perspiration is our body's natural way of cooling us down. We may feel the heat more when we sweat but the truth is that the body is cooling itself by releasing all the built in heat. Our body needs to maintain a normal temperature of 98.6 Fahrenheit failing which we are likely to suffer a heart stroke. Sweat is released through small holes known as pores in our skin. When sweat comes in contact with the atmosphere, it evaporates leaving a cool feeling behind. Sweat is almost made of water with small amounts of chemicals like ammonia, urea, sugar and body salts like sodium . Our body has approxima...

Why are tomatoes red?

Why are tomatoes red? Tomatoes are a significant ingredient in several food preparations. Whether they are used in a sauce, solid, puree or gravy form, tomatoes are a delicious and juicy treat. When tomatoes are raw, they are green in colour. However, the moment they start ripening they change colour and turn red. Have you ever wondered why this happens? Let us find out... What renders the red colour to tomatoes? Tomatoes have the chlorophyll pigment when they are raw and hence they are green in colour. As they start ripening, the pigment lycopene becomes dominant and this is why tomatoes turn red. Lycopene is a carotenoid and belongs to the same family as beta-carotene . It is a powerful antioxidant that neutralizes free radicals; especially those derived from oxygen. It is highly unsaturated hydrocarbon and contains 11 conjugated and 2 unconjugated double bonds making it longer than any other carotenoid. Lycopene obtained from plants tends to exist in a...
