Nucleic acid | Definition, Function, Structure, & Types | Britannica
nucleic acid, naturally occurring chemical compound that serves as the main information-carrying molecule of the cell and that directs the process of protein synthesis, thereby determining the inherited characteristics of every living thing.
Nucleic acid - Wikipedia
Nucleic acids are chemical compounds that are found in nature. They carry information in cells and make up genetic material. These acids are very common in all living things, where they create, encode, and store information in every living cell of every life-form on Earth.

核酸（英語： nucleic acid ）是一种通常位于细胞内的大型生物分子，主要負責生物体遗传信息的携带和传递。 核酸有兩大類，分別是 脱氧核糖核酸 （DNA）和 核糖核酸 （RNA）。
Nucleic acid - Definition and Examples - Biology Online
2023年5月12日 · A nucleic acid is a biomolecule that stores and transmits genetic information in living organisms. Nucleic acids are composed of nucleotides, which, in turn, are made up of sugar, phosphate group, and nitrogenous base. There are two types of nucleic acids: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Overview:
Understanding biochemistry: structure and function of nucleic …
Nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.

3 天之前 · RNA is the nucleic acid responsible for using the genetic information in DNA to produce proteins. Nucleotides are joined together to form nucleic acids through the phosphate group of one nucleotide connecting in an ester linkage to the OH group on the third carbon atom of the sugar unit of a second nucleotide.

2024年8月5日 · Nucleic acids are molecules that allow organisms to transfer genetic information from one generation to the next. These macromolecules store the genetic information that determines traits and makes protein synthesis possible. Two nucleic acid examples include deoxyribonucleic acid (better known as DNA) and ribonucleic acid (better known as RNA).
