Solution

The correct option is A Dipicolinic acid
Endospores are the thick-walled dormant cells with the core containing DNA, RNA, proteins and dipicolinic acid associated with calcium ions. The calcium-dipicolinic acid complex is present in its core. This complex imparts heat resistance and stability to its DNA.
Thus, the correct answer is option B.

The following picture shows a bacterial lawn in an agar plate with few clear zones. The zones are formed due to a chemical present in the disk at the centre of each zone. This chemical brings about a breakdown of bacterial cells and hence the clear zones. What is this chemical called and what are the primary sources of it?
