DNA VS. RNA

DNA (Deoxyribonucleic Acid) and RNA (Ribonucleic Acid) are both nucleic acids that play vital roles in storing and transmitting genetic information in living organisms. They are polymers made up of monomers called nucleotides, each consisting of a sugar (ribose for RNA or deoxyribose for DNA), a phosphate group, and a nitrogenous base (adenine, thymine, guanine, or cytosine for DNA; uracil, adenine, guanine, or cytosine for RNA). DNA is the genetic material found primarily in the nucleus of eukaryotic cells . Its double-stranded helical structure is composed of four nitrogenous bases attached to the sugars and phosphates. The two strands are antiparallel, meaning that they run in opposite directions and are bound together by hydrogen bonds between complementary nucleotide bases (adenine pairs with thymine, and guanine pairs with cytosine). DNA is responsible for storing genetic information in the form of genes, which code for proteins and other cellular components. RNA , on the other
