Stages of Protein Synthesis: Transcription and Translation

The video explains protein synthesis, focusing on transcription and translation. It begins with an overview of how DNA codes for proteins through sequences of bases forming codons. Transcription occurs in the nucleus, where RNA polymerase creates mRNA from DNA. The video highlights RNA's differences from DNA, such as being single-stranded and using uracil instead of thymine. Translation follows, where mRNA is read by ribosomes in the cytoplasm, and tRNA brings amino acids to form polypeptides. The video concludes with a summary of these processes, emphasizing the importance of protein structure for cellular functions.
