What are the roles of DNA and RNA in living organisms, and how do they contribute to the process of protein synthesis?
Understand the Problem
The question appears to be discussing foundational concepts related to DNA and its role in genetics, including the structure of DNA, its replication, and the processes involved in protein synthesis.
Answer
DNA holds genetic info; RNA translates it into proteins via mRNA, tRNA, and rRNA.
DNA carries the genetic information needed for the development and functioning of living organisms, serving as a template for RNA synthesis. RNA acts as a messenger (mRNA), adapter (tRNA), and component of ribosomes (rRNA) in protein synthesis, translating the genetic code into proteins.

More Information
DNA serves as a blueprint for all cellular functions and heredity, while RNA facilitates various roles in the synthesis of proteins, which are crucial for cellular structure and function.
Tips
A common mistake is confusing the roles of different types of RNA in protein synthesis. Remember that mRNA is the messenger, tRNA is the adaptor, and rRNA is part of the ribosomal structure.
