Which of the following molecules are not involved in translation?*1 pointpolypeptide chaintRNAmRNARNA polymerase

The molecule that is not involved in translation is RNA polymerase. Here's why:

1. Polypeptide chain: This is the primary product of translation. The ribosome reads the mRNA and translates it into a polypeptide chain, which will later fold into a functional protein.

2. tRNA (transfer RNA): This is a key player in translation. Each tRNA molecule carries an amino acid to the ribosome, where it is added to the growing polypeptide chain.

3. mRNA (messenger RNA): This is the template for translation. It carries the genetic information from the DNA to the ribosome, where it is read and translated into a protein.

4. RNA polymerase: This enzyme is not involved in translation, but in transcription. It synthesizes the mRNA from the DNA template. Once the mRNA is synthesized, it leaves the nucleus and goes to the ribosome for translation. So, RNA polymerase is not directly involved in the process of translation.
