Nucleic Acids | Biological Molecules Simplified #3


Thanks for stopping by this is two minute classroom and today we’re talking about nucleic acids You may have heard about nucleic acids when talking about DNA or RNA Because the NA literally stands for nucleic acid This is where genetic information is stored and allows cells to produce all the necessary protein structures in living organisms I’m going to introduce the basic structure of nucleic acids first and Then talk about the variations for structure and how that relates to their function Monomers of nucleic acids are called nucleotides These are the basic unit of nucleic acids that bond together to form RNA and DNA All nucleotides are made up of three main components a phosphate group a sugar and a nitrogenous base In RNA and DNA the phosphate group is the same, but they have slightly different sugars In RNA the sugar is ribose and in DNA the sugar is also a ribose but with one less oxygen hence, RNA is ribonucleic acid and DNA is Deoxyribonucleic acid because the ribose has been deoxygenated Finally we have the nitrogenous base and if you’ve studied DNA at all, you probably remember these the nitrogenous bases in DNA are guanine adenine cytosine and thymine RNA also has guanine adenine and cytosine but instead of thymine RNA contains uracil The phosphates of nucleic acids bond together to form long poly nucleotide chains like RNA and DNA the nitrogenous bases can form weaker hydrogen bonds as they do between two strands of DNA this bonding gives DNA It’s helical structure and allows it to perform many important functions Nucleic acids are an underrated molecule in my opinion Carbohydrates proteins and fats seem to get all the attention but nucleic acids store all the genetic information for your cells Without them your body wouldn’t build the necessary machinery to carry out all cellular functions I hope this video answered any questions you had if you still have some I love to reply to my comments So send additional questions there. You should also check out my video on DNA vs RNA which goes into more detail and don’t forget to smash that like button and subscribe for more quality content. I’ll catch you next time

  1. Could you pleaseeeee make a video on acid, base, pH and pOH, and how to determine the concentration of hydronium and hydroxide ions? Like, please
