Detailed explanation-1: -The flow of information from DNA to RNA to proteins is one of the fundamental principles of molecular biology. It is so important that it is sometimes called the “central dogma.” Through the processes of transcription and translation, information from genes is used to make proteins.

Detailed explanation-2: -What does DNA do? DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.

Detailed explanation-3: -A : A section of DNA that provides information for one protein is called gene for that protein.

Detailed explanation-4: -The information needed to produce proteins, as seen via transcription, is stored within the DNA (deoxyribonucleic acid) of a cell. Furthermore, in eukaryotes, DNA is stored within the nucleus, where within prokaryotes, it is found within DNA aggregates within nucleoli.

Detailed explanation-5: -Proteins are the key working molecules and building blocks in all cells. They are produced in a similar two-step process in all organisms called protein synthesis – DNA is first transcribed into RNA, then RNA is translated into protein.
