Final answer:

The peptidyl transferase enzyme, known as a ribozyme, is part of the large ribosomal subunit and crucial for protein synthesis. It is not DNA Polymerase, RNA Ligase, RNase, or Reverse Transcriptase, which have different cellular functions.

Step-by-step explanation:

The enzyme that is known as the peptidyl transferase, which also functions as a ribozyme, is a component of the large ribosomal subunit. This ribozyme is crucial for the process of translation as it catalyzes the formation of peptide bonds between amino acids, effectively lengthening the growing polypeptide chain during protein synthesis. It is not one of the enzymes listed in the question options (DNA Polymerase, RNA Ligase, RNase, or Reverse Transcriptase), as these serve different functions within the cell. Specifically, reverse transcriptase is seen in retroviruses like HIV and is responsible for transcribing RNA back into DNA, whereas DNA polymerases, RNA ligases, and RNases have roles in DNA replication, RNA splicing, and RNA degradation respectively.

The peptidyl transferase enzyme, also known as a ribozyme, is a component of the ribosome that catalyzes the formation of peptide bonds during protein synthesis. It is responsible for linking amino acids together in a growing polypeptide chain.
