Lenski chose an " E . coli " strain that reproduces only asexually, lacks any plasmids that could permit bacterial conjugation, and has no viable prophage.

It seems likely that the plasmid pHK2 may be a virus that can form circular plasmids and that the region within " Haloferax volcanii " is a prophage.
23.
Furthermore, " D " . " lykanthroporepellens " has a prophage region containing 45 hypothetic proteins, which accounts for roughly 4 % of the chromosome.
24.
Because this prophage can be present in tandem in some biotypes of " V . cholerae ", horizontal and vertical transmission of the genetic material from CTX? are not mutually exclusive.
25.
A process known as lysogenic or phage conversion changes the properties of the bacteria cell; this is possible because the prophage itself contains genes that can present new properties into the bacteria cell or host cell.

When the partially encapsulated phage material infects another cell and becomes a " prophage " ( is covalently bonded into the infected cell's chromosome ), the partially coded prophage DNA is called a " heterogenote ".

Today, Agenus is focused on developing a range of immuno-oncology products, including the Prophage vaccines, multiple checkpoint modulators ( also known as checkpoint inhibitors or checkpoint antibodies ) and its QS21-Stimulon adjuvant.

However, when the Hfr parent was lysogenic, lysogeny ( i . e ., the prophage ) was not inherited by any of recombinants, which were recovered by growing them as colonies on the appropriate agar medium.

Esther Lederberg's discovery of F stemmed directly from her experiments to map the location of lambda prophage on the " E . coli " chromosome by crosses with other " E . coli " strains with known genetic markers.
