Which antiviral acts as a chain terminator?

  #2

Zidovudine is a thymidine analog that inhibits the viral reverse transcriptase as a chain terminator.

  #3

Yes besides Zidovudine (AZT), other reverse transcriptase like Didanosine (DDI) and Zalcitabine (DDC) will act like chain terminators if incorportated into DNA. Also Acyclovir acts as a chain terminator.
