Answer 2

The answer is DNA and RNA.  

Both DNA and RNA are the nucleic acids that play an essential function in the life of an organism. Though, both DNA and RNA function in harmony, they exhibit huge differences, that is, why both these do not exhibit direct relationship.  

When suggesting towards a free efficient expression binds them, one is referring towards gene expression. It is the procedure, which assists in obtaining proteins from genes, whose ultimate phase is a synthesis of proteins, this binds both DNA and RNA.
