The structure of DNA (Deoxyribonucleic acid) and RNA (Ribonucleic acid) is fundamental to understanding how genetic information is stored and transmitted in living organisms. Here's a brief overview of their structures: Nucleotides: Each nucleotide in DNA is made up of a sugar called deoxyribose, a phosphate group, and one of four nitrogenous bases: adenine (A), thymine (T), cytosine (C), or guanine (G). Base Pairing: In DNA, the bases pair up in a specific way: adenine with thymine (A-T) and cytosine with guanine (C-G). Function: DNA stores genetic information that dictates the development and functioning of living organisms. Nucleotides: RNA nucleotides contain the sugar ribose, a phosphate group, and one of four nitrogenous bases: adenine (A), uracil (U), cytosine (C), or guanine (G). Base Pairing: In RNA, adenine pairs with uracil (A-U) instead of thymine. Function: RNA plays various roles, including acting as a messenger carrying instructions from DNA for controlling the synthesis of proteins.
