According to the central dogma, which of the following represents the flow of genetic information in cells?

protein to DNA to RNA

DNA to RNA to protein

RNA to DNA to protein

DNA to protein to RNA

DNA to RNA to protein.

Explanation:

Central dogma in biology was given by Crick in 1957. The central dogma explains the flow of genetic information in the cells.

According to the central dogma, DNA can multiply and increase its number by the process of replication. The information from DNA is changes to RNA by the process of transcription. The expression of protein product expression occur from the RNA by the process of translation. Hence, the information travels from DNA to RNA to protein.

Thus, the correct answer is option (2).
