This short video describes the structure and function of nucleic acids. Review the following table for similarities and differences between DNA and RNA. Conditions varying the blood level of uric acids: Whenever there is cell death, the nucleic acids are released and converted to purines and finally uric acid is formed. The name "nucleic acid" comes from the fact that they were first described because they actually had acidic properties, much like the acids that you know. ", The Mechanism of Action of Vitamin B12 in the Human Body. It creates DNA and RNA, which store the information needed by cells to create proteins. What does nucleic acid contains? In your cell’s nucleus, the information in a gene is transferred to a molecule of mRNA in a process called transcription. There are two types of cell division in your body called mitosis and meiosis. Nucleic Acids -> Nucleotides -> Uric acid (Excreted in the urine) The nucleotides are broken down into uric acid and this is the second major organic waste product that we excrete in our urine. So the sequence of these molecules in the polymer can convey "make a protein", "please replicate me", "transfer me to the nucleus..." The other amazing part about nucleic acid is that they're very stable proteins. There is a specific tRNA for almost every different amino acid, and the tRNA’s link amino acids together in a chain to form a protein. Eukaryotic Cell: Mitosis, Not Just Open or Closed, The Cell – A Molecular Approach, Second Edition; Geoffrey M. Cooper. Nuclein is the material found in the nucleus, consisting mainly of nucleic acids, protein, and phosphoric acid. The nucleic acids are made out of five primary elements: phosphorus, nitrogen, oxygen, carbon, and hydrogen. If you have children, your genetic information will be recombined and united with your partner’s genetic information to yield genetic information that will be stored in thenucleus of every cell in your child’s body. Proteins are constructed through an intricate action blueprinted and carried out by the nucleic acids deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). And so if you think about the need to convey genetic information from one cell to another, you would want a molecule that is very stable and doesn't fall apart on its own, and that's a major feature of nucleic acids. "Nucleic acid" is the term we use to describe specific large molecules in the cell. The nucleic acids are macromolecules that contain the hereditary information necessary for life. The conditions where uric acid level increases in the blood are: (a) Excessive tissue destruction and (b) Gout. Dictate amino-acid sequence in proteins.
