Replication \Rep`li*ca"tion\ (-k?"sh?n), n. [L. replicatio. See {Reply}.] 1. An answer; a reply. --Shak.

2. (Law Pleadings) The reply of the plaintiff, in matters of fact, to the defendant's plea.
3. Return or repercussion, as of sound; echo.
To hear the replication of your sounds. --Shak.
4. A repetition; a copy.
5. (Biochem.) The copying, by enzymes, of a cell's genome, i.e. the DNA or RNA comprising its genetic material, so as to form an identical genome. This is an essential step in the division of one cell into two. This differs from {transcription}, which is the copying of only part of the genetic information of a cell's genome into RNA, as in the processes of biosynthesis of messenger RNA or ribosomal RNA. [PJC]
Syn: Answer; response; reply; rejoinder.
Both are classed as "nucleoside analogues," or false building blocks of DNA that insert themselves into the virus and interrupt its replication.
What he is celebrating is what he calls "blind replication," as in the way DNA duplicates itself.
The compound they used, a phosphorothioate that nullifies a gene essential to HIV's replication cycle, was found to inhibit significantly HIV's replication and cell-killing power in the test tube.

A chemical cousin of AZT, DDI is a nuceoside analog, a false building block of DNA that gets into the virus's genetic material and blocks its replication.
The team hasn't yet published its recipe for making the new molecule, which may delay replication of the results by other scientists.
