What is the role of DNA and RNA in protein synthesis?

Protein synthesis is done in multiple steps, namely transcription first, then translation. Transcription entails the use of DNA as a template to form messenger RNA (mRNA), which is then used in translation along with transfer RNA (tRNA) to create proteins. DNA can also have structural and immunological functions.

How is information transferred from DNA → RNA → protein?

In transcription, the information in the DNA of every cell is converted into small, portable RNA messages. During translation, these messages travel from where the DNA is in the cell nucleus to the ribosomes where they are 'read' to make specific proteins.
