Answer:
E) Both Bacillus and Clostridium.
Explanation:
Bacterial endospores production is part of its survival mechanism. Bacteria produces these highly resistant spores that lies dormant in vegetative state, used during unfavourable and stressful environmental conditions. They are produced by gram positive bacteria such as Bacillus and Clostridium, and can lay dormant for years. Endospores are non-reproductive structures resistant to radiations, starvation and chemical disinfectants.
In eukaryotes, DNA is found in chromosomes in the nucleus. Chromosomes are made of a single molecule of DNA and proteins. Chromosomes are linear, and DNA in them is double stranded. There are many chromosomes in a single nucleus. In prokaryotes, a single DNA molecule which is double stranded forms the chromosome. There are no proteins in the chromosome. In viruses, the genetic material is either DNA or RNA. They may be double stranded or single stranded. It may be circular or linear.
