Detailed explanation-1: -In eukaryotes, transcription occurs in the nucleus. Following RNA processing, RNAs exit the nucleus to the cytoplasm where they are utilized. mRNAs in particular carry the information for protein sequences. Thus mRNAs are used to convey genetic information from the nucleus to the cytoplasm.

Detailed explanation-2: -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.”

Detailed explanation-3: -The basic flow of genetic information in biological systems is often depicted in a scheme known as “the central dogma” (see figure below). This scheme states that information encoded in DNA flows into RNA via transcription and ultimately to proteins via translation.

Detailed explanation-4: -The central dogma of molecular biology explains the flow of genetic information, from DNA? to RNA?, to make a functional product, a protein?. The central dogma suggests that DNA contains the information needed to make all of our proteins, and that RNA is a messenger that carries this information to the ribosomes?.
