Answer:
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).
a volcano is a mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapor, and gas are being or have been erupted from the earth's crust.
There are three main types of volcano - composite or strato,shield and dome. Composite volcanoes, sometimes known as strato volcanoes, are steep sided cones formed from layers of ash and [lava] flows. The eruptions from these volcanoes may be a pyroclastic flow rather than a flow of lava.
