Protein Synthesis

The video tutorial explains how DNA codes for proteins through the processes of transcription and translation. It begins with an overview of DNA's role in coding for amino acids, which form proteins. The transcription process is detailed, where RNA polymerase binds to DNA to create mRNA. This mRNA then leaves the nucleus and enters the translation stage in the cytoplasm, where ribosomes read the mRNA to assemble amino acids into a polypeptide chain. The polypeptide folds into a specific protein shape, enabling it to perform its function in the body. The tutorial concludes with a recap of these processes.
