To solve this problem, we need to identify the enzyme that can catalyze initiation, elongation, and termination in prokaryotic transcription. Let's analyze each option:$\newline \bullet$Option 1: DNA dependent DNA polymerase$\newline$ - This enzyme is involved in DNA replication, not transcription. It synthesizes a new DNA strand using a DNA template.$\newline$ - It does not participate in transcription processes such as initiation, elongation, or termination.$\newline \bullet$Option 2: DNA dependent RNA polymerase$\newline$ - This enzyme is responsible for synthesizing RNA from a DNA template during transcription.$\newline$ - In prokaryotes, a single type of RNA polymerase catalyzes all three stages of transcription: initiation, elongation, and termination.$\newline$ - Therefore, this is the correct enzyme that fulfills the given criteria.$\newline \bullet$Option 3: DNA Ligase$\newline$ - DNA ligase is involved in joining DNA fragments during replication and repair.$\newline$ - It does not play a role in transcription.$\newline \bullet$Option 4: DNase$\newline$ - DNase is an enzyme that degrades DNA molecules.$\newline$ - It is not involved in the transcription process.$\newline$Based on the analysis, the enzyme that can catalyze initiation, elongation, and termination in prokaryotic transcription is DNA dependent RNA polymerase.$\newline$Therefore, the correct option is Option 2.
