Question

PVC stands for
A. Plantomycetes, Verrucomicrobia, Clostridium
B.Pteridophyta, Verrucomicrobia, Clostridium
C. Plantomycetes, Verrucomicrobia, Chlamydiae
D.None of the above

Answer 1

Hint: The PVC superphylum, along with the Lentisphaerae, Poribacteria, and two other nominee divisions, is an amalgamation of species from the phyla. There is no significant marker that differentiates them from other bacteria in the various species of this superphylum.

Complete answer:
First we should know about PVC to answer this question. The PVC superphylum is a class of different domain bacterial phyla originally proposed on the basis of the sequence analysis of the 16S rRNA gene.
Now, let us find the solution-
The superphylum of PVC is an assemblage of Planctomycetes, Verrucomicrobia, and Chlamydiae phyla species. Due to the pathogenic ability in humans and in animals, members of the Chlamydiae phylum are one of the most widely studied microorganisms. Many human diseases, including sexually transmitted urinary tract infections, trachoma, and pneumonia, are caused by them. Planctomycetes phylum organisms are noted for their peculiar cellular properties, such as sterol biosynthesis, internal compartmentalization, and endocytosis-analogous pathways normally associated with eukaryotesis.
From these we came to know that options A, B, and D are incorrect.

Hence, the correct answer is option (C)

Note: For biotechnology, evolutionary cell biology, ecology and human wellbeing, the PVC superphylum is of concern. A number of typical bacterial characteristics are absent in some PVC specimens, while others have features that are typically more related to eukaryotes or archaea. The Planctomycetes phylum, for example, is atypical for the lack of FtsZ protein and the existence of an endomembrane mechanism that has been established.
