Depending upon the chemical nature of the template ($DNA$ or $RNA$) and the nature of nucleic acids synthesized from it ($DNA$ or $RNA$),list the types of nucleic acid polymerases.

(N/A) There are two main types of nucleic acid polymerases based on the template and the product:
$1$. $DNA$-dependent $DNA$ polymerases: These enzymes use a $DNA$ template to synthesize a new strand of $DNA$. They are primarily involved in $DNA$ replication.
$2$. $DNA$-dependent $RNA$ polymerases: These enzymes use a $DNA$ template to synthesize $RNA$. They are primarily involved in the process of transcription.
