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...

How to Make Fake Snow! Missing out on white Christmas because you live in a country where there is no snow? Well, here's a solution! You can make your own Fake Snow! What is Fake Snow? Fake snow looks very similar to the actual snow and is non-toxic in nature. It is made out of polymer and gives you a cool feel when you touch it, just like real snow. The ingredients and procedure to prepare fake snow are simple. Things that you need to make fake snow: a) Common polymer or sodium polyacrylate b) Water You will find sodium polyacrylate or common polymer in disposable diapers or as crystals in your garden as it helps in keeping the soil of the garden moist. Here is how you make it: To prepare fake snow, all you have to do is add water to sodium polyacrylate or common polymer. It will take the form of a gel . Keep adding water till it is completely moist. The more water you add, the slushier the gel of sodium polyacrylate or common polymer will b...

Chemistry of everyday life

In this lens I'd like to talk you about the Chemistry of daily life. Chemistry is an exciting experimental science which lets us to understand our world and makes our life easier. As you will read in the following articles, chemistry is in our everyday life: in our body, at home, in the nature... in every second of our lives! How soap cleans? There are substances which can be dissolved in water (salt for example), and others that can't (for example oil). Water and oil don't mix together, so if we try to clean an oily stain from a cloth or from the skin, water is not enough. We need soap. Soap is formed by molecules with a "head" which likes water (hydrophilic) and a long chain which hates it (hydrophobic) . Because of this dualism, soap molecules act like a diplomat, improving the relationship between water and oil. How? When soap is added to the water, the hydrophilic heads of its molecules stay into the water (they like it!), while the l...
