Imagine your DNA as the blueprints for your body, containing all the instructions it needs to function and grow. But how does this blueprint get translated into the physical traits and characteristics that make up who you are? The answer lies in the central dogma of molecular biology.
The central dogma describes the three-step process by which the information encoded in DNA is used to create proteins, the building blocks of life. This process involves transcription and translation, which are like molecular messengers that carry the genetic code from DNA to RNA and then to proteins.
Let’s break it down step by step:
Transcription: DNA to RNA
Think of transcription as the process of copying down the instructions from the DNA blueprint. During transcription, a special enzyme called RNA polymerase binds to a specific region of DNA and starts copying the sequence of nitrogenous bases (A, C, G, T) into a new molecule called messenger RNA (mRNA). This mRNA is then released from the DNA and travels out of the nucleus.
Translation: RNA to Protein
Now comes the second step: translation. This is where the mRNA takes the genetic code to the ribosome, a molecular machine that reads the code and assembles it into a protein. This process involves transfer RNA (tRNA), which brings the appropriate amino acids to the ribosome based on the sequence of codons (three-base segments) in the mRNA. Each codon corresponds to a specific amino acid, and the order of amino acids determines the structure and function of the protein.
