Biology

1. DNA Is the Carrier of Genetic Information
DNA contains genes, which are the instructions for making proteins.
Through transcription, parts of DNA serve as templates to synthesize RNA (such as mRNA), just like making a copy of the information in DNA.

2. Protein Synthesis Is Based on the Information of RNA
The generated mRNA leaves the nucleus (in eukaryotic cells) and arrives at the ribosomes.
During translation, the information of mRNA is used to assemble amino acids into polypeptide chains, which then fold into protei...
