DNA to RNA to Protein
|
|
|
Protein to RNA to DNA
|
|
|
RNA to Protein to DNA
|
|
|
DNA to Protein to RNA
|
Explanation:
Detailed explanation-1: -The RNA sequence of ribonucleotides is translated into an amino acid sequence of polypeptides by the process of translation. Thus the flow of genetic information is unidirectional and follows the path: DNA–>RNA–>protein.
Detailed explanation-2: -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-3: -Thus, during expression of a protein-coding gene, information flows from DNA
