Building Blocks Of Nucleic Acid
What Are the Edifice Blocks of Nucleic Acids?
Nucleic acids are made up of three components: a phosphate, a sugar and a nitrogenous base. The specific edifice blocks of DNA and RNA are slightly different, but they fall into the same three categories.
The framework of a nucleic acid is the carbohydrate-phosphate backbone. As the name suggests, this structure is a string of linked sugar and phosphate molecules that requite the nucleic acid a "skeleton." Each individual unit of nucleic acid, called a nucleotide, contains one sugar molecule and one phosphate molecule that link to the sugars and phosphates in other nucleotides to create a chain in which sugars and phosphates alternate. Ribose is the sugar present in RNA, and deoxyribose is the saccharide nowadays in DNA.
The other part of each nucleotide is one nitrogenous base attached to the sugar molecule. The nitrogenous bases serve equally the units of data in nucleic acids. There are five different nitrogenous bases, and their arrangement in a chain of DNA or RNA stores data just as an arrangement of letters makes a word. The nitrogenous bases used in DNA are adenine, thymine, cytosine and guanine. Strands of RNA contain uracil instead of thymine, only the other iii bases are the same.
