The Central Dogma of Biology: From Gene to Protein

TLDRChromosomes are made up of long strands of DNA, which contain genes that code for proteins. The process of going from the gene to the protein is called the central dogma of biology. It involves transcription, where the gene is transcribed into messenger RNA (mRNA), and translation, where the mRNA is translated into a polypeptide sequence. The ribosome plays a crucial role in the translation process, as it matches tRNA molecules to the appropriate codons on the mRNA, allowing the amino acids to form a polypeptide chain.
