a complex organic substance present in living cells, especially DNA or RNA, responsible for carrying genetic information
What is "nucleic acid"?
Nucleic acids are crucial molecules found in all living organisms, playing a central role in storing and transmitting genetic information. They come in two main forms: DNA and RNA. DNA holds the genetic instructions necessary for an organism's development, growth, and functioning, while RNA acts as a messenger, carrying out DNA's instructions to produce proteins. These molecules are made up of smaller units called nucleotides, each consisting of a sugar, a phosphate group, and a nitrogenous base. The sequence of these bases determines the unique genetic code of an individual, influencing traits and characteristics.
