Answer:

maybe?

Explanation:

Characteristics of Clostridium Tetani

Clostridium tetani is an obligately anaerobic bacillus that is gram positive in fresh cultures but may have variable staining in older cultures or tissue samples.25 The complete genome of the organism has been sequenced, and its products were recently compared with other clostridia.26 During growth, the bacilli possess abundant flagella and are sluggishly motile. Two toxins, tetanospasmin (commonly called tetanus toxin) and tetanolysin, are produced during this phase. Tetanospasmin is encoded on a plasmid that is present in all toxigenic strains.

Answer:a) decreased chromatin condensation

Explanation:

During eukaryotic cell division a chromatin becomes obvious and it is simply a mass of genetic material made up of DNA and proteins which condenses to form chromosomes.

The chromatin primarily function in the compression the DNA into a unit so compacted that will be so tiny and can fit within the nucleus.

Chromatin condensation is driven by condensins and interactions between histones.

Condensins however, are large protein complexes whose central role in cell division is chromosome organization and segregation.

Chemical manipulation as stated above is decreases the rate of chromatin condensation.
