Answer:
Step-by-step explanation:
DNA, or deoxyribonucleic acid, is the molecule that stores and transmits genetic information in all living organisms. Genetic information is stored in the sequence of nucleotides, the building blocks of DNA. Each nucleotide is made up of a sugar, a phosphate group, and a nitrogenous base. There are four types of nitrogenous bases in DNA: adenine (A), thymine (T), guanine (G), and cytosine (C).
The specific sequence of these bases along the DNA strand is what encodes the genetic information. For example, the sequence ATGCAGA might code for a specific protein, while the sequence GACATAG might code for a different protein. These sequences of bases are stored in specific regions of the DNA called genes.
The genetic information is transmitted during cell division, when the DNA is replicated, and during protein synthesis, when the information in the DNA is used to build the specific proteins determined by the genetic code.
