Is telomerase a DNA polymerase?

Yes, telomerase is a type of DNA polymerase, but it is a specialized one. Unlike other DNA polymerases, which synthesize new DNA based on a DNA template, telomerase synthesizes DNA by using an RNA template. This RNA component of telomerase allows it to add repetitive DNA sequences to the telomeres at the ends of chromosomes. This process helps maintain telomere length during DNA replication, compensating for the normal shortening that occurs with cell division.
