Question
The central dogma of molecular biology states that in a cell, information flows from DNA to RNA to protein.
Solution
The central dogma of molecular biology states that in a cell, information flows from DNA to RNA to protein. This process consists of two key stages: transcription and translation.
-
Transcription: This is the first step where the information encoded in DNA is transcribed to messenger RNA (mRNA). During transcription, the DNA strands unwind and separate, and one of the strands serves as a template for synthesizing mRNA.
-
Translation: The second step is translation, where the mRNA is decoded by ribosomes to synthesize proteins. The ribosomes read the sequence of codons in the mRNA, and transfer RNA (tRNA) molecules bring the corresponding amino acids to build the polypeptide chain, ultimately forming a functional protein.
This flow of genetic information is fundamental to cellular function, allowing cells to express genes and produce the proteins necessary for life.
