nucleic acid
Plural
nucleic acids
1
a complex organic substance present in living cells, especially DNA or RNA, responsible for carrying genetic information
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.
- Nucleic acid, like DNA, holds genetic instructions for living organisms.
- Nucleic acids in the cell nucleus transmit genetic information during cell division.
- Studying nucleic acids helps understand the diversity of life.
- DNA's double helix structure is a hallmark of nucleic acids.
- Genetic research relies on decoding the intricate sequences of nucleic acids.
