Verified step by step guidance1
Begin by understanding 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. This is a fundamental concept in molecular biology.
First, DNA is transcribed into RNA. This process is known as transcription, where the DNA sequence is copied into a complementary RNA sequence.
Next, RNA is translated into Protein. This process is called translation, where the RNA sequence is used to synthesize proteins by assembling amino acids in the correct order.
Remember that the sequence DNA → RNA → Protein is the correct order of information flow according to the central dogma, emphasizing the roles of transcription and translation.
