A study created to make genetically modified orginisms.
Answer:the correct option is B
(Streptococcus).
Explanation:
Acute necrotizing ulcerative gingivitis (ANUG) occurs due to poor oral hygiene which encourages plaque to form on teeth, causing inflammation of the surrounding gum tissues. The microorganisms that are known to inhabit the damaged tissues are oral spirochaete which includes Borrelia,Fusobacteria, Bacteroidese and Peptostreptococcus. Streptococcus is not an oral spirochaete therefore is excluded. I hope this helps.
Answer:
A normal type of white blood cell that has coarse granules within its cytoplasm.
In prokaryotes, horizontal gene transfer (HGT), the transfer of genetic material from one organism to another organism within the same generation, is an important way to promote genetic diversity. HGT allows even distantly related species to share genes, influencing their phenotypes.
Transformation: Mode of genetic transfer in which “bare DNA” is taken up from the environment is taken up by cells
Transduction: Mode of genetic transfer in which genes are transferred by a bacteriophage to a bacterial cell
Conjugation: Mode of genetic transfer in which two cells must come in contact and genetic material is transferred to a recipient cell from a donor cell through its pili
