1. When the riddle says "both have<em> no direct relationship</em>", it refers to that although DNA and RNA work hand in hand, <u>they have large differences that help them complement and function</u>.
2. When we talk about "a free efficient <em>expression binds them</em>" we refer to gene expression. It is the process that allows you to obtain proteins from genes, <u>whose final stage</u> is the synthesis of proteins, <u>which binds both</u> DNA and RNA.
DNA (deoxyribonucleic acid) is a molecule made up of two chains that coil around each other and carries the genetic instructions of all known living organisms. On the other hand, RNA (ribonucleic acid) is a polymeric molecule basic for coding, decoding, regulation and expression of genes.
The game states that DNA and RNA have no direct relationship, but collaborate. The "expression" refers to gene expression.
