The document summarizes the processes of transcription and translation. It defines key terms like DNA, RNA, genes, and proteins. It describes transcription as using RNA polymerase to create mRNA from DNA in the nucleus, with mRNA carrying codon instructions. Translation occurs in the cytoplasm, using tRNAs to bring amino acids to the ribosome according to mRNA codons, forming a protein chain. The final product of transcription is mRNA, while the final product of translation is an amino acid chain.
