Transcription is the process of copying information from DNA to mRNA. Translation is the process of using the mRNA code to assemble a protein. The genetic code links codons, which are three nucleotide sequences in mRNA, to specific amino acids. tRNA molecules match codons to their corresponding amino acids and deliver them to the ribosome for protein assembly.

1. Transcription and Translation Transcribe: to copy using the same “DNA language” of nitrogen bases (ATCG or AUCG) Translate: to take from the “DNA language” of bases to a different language – “amino acid language” which is made of codons.
