Verified step by step guidance1
Understand the central dogma of molecular biology, which describes the flow of genetic information within a biological system.
The central dogma states that genetic information flows from DNA to RNA to protein.
First, DNA is transcribed into RNA. This process involves copying a segment of DNA into RNA by the enzyme RNA polymerase.
Next, the RNA is translated into protein. During translation, the RNA sequence is used to synthesize a specific protein with the help of ribosomes and transfer RNA (tRNA).
Evaluate the given statements against the central dogma: The correct statement is 'DNA is transcribed into RNA, which is then translated into protein.'
