Which of the following best describes the flow of information in a cell?
|
|
mRNA
|
|
|
tRNA
|
|
|
DNA
|
|
|
protein
|
Explanation:
Detailed explanation-1: -To manufacture protein molecules, a cell must first transfer information from DNA to mRNA through the process of transcription. Then, a process called translation uses this mRNA as a template for protein assembly.
Detailed explanation-2: -Central dogma. The central dogma of molecular biology is a theory stating that genetic information flows only in one direction, from DNA, to RNA, to protein, or RNA directly to protein.
Detailed explanation-3: -Thus, during expression of a protein-coding gene, information flows from DNA → RNA → protein. This directional flow of information is known as the central dogma of molecular biology.
