Mutations are spontaneous and occur at random however there are some mutagenic agents which increase the chance of this happening such as radiation exposure. If it is a point shift mutation then only a few bases on the dna sequence are changed so only changes a few of the amino acids in that chain (such as inversion of a base). If its a frame shift then the base sequence is altered so much so that every amino acid from after that changes (such as deletion of a base) which can create things such as cri-du-chat syndrome which results from a piece of chromosome 5 is missing. Hope this helps:)

After staining endospores will be green in a parent cell.
Staining endospore is difficult as the bacteria do not allow stains to be
attach to the spore. This is why there is a need to use heat to let the main
stain which is Malachite green into the endospore.
