Nucleic acids: Chemical composition of DNA and RNA
A nucleic acid is a molecule that contains a backbone of sugar, phosphate groups, and nitrogenous bases. There are two main types of nucleic acids: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is found in the nucleus of cells and contains the genetic code for an organism. RNA is found in the nucleus of cells and is involved in protein synthesis.
DNA is a molecule that is responsible for the storage and transmission of genetic information. It is composed of two strands of nucleotides that are twisted around each other to form a double helix. Each nucleotide is a molecule that contains a deoxyribose sugar backbone and a nitrogenous base. The bases on the DNA backbone are complementary to the bases on the RNA backbone, meaning that they have the same shapes but different chemical properties.
RNA is a molecule that is responsible for the translation of DNA into proteins. It is composed of a single strand of nucleotides that is folded into a double helix. Each nucleotide on the RNA backbone is complementary to a nucleotide on the DNA backbone, but the bases on the RNA backbone are different from the bases on the DNA backbone. This allows RNA to read the genetic code in DNA and use it to synthesize proteins
