A common laboratory technique used to make many copies (millions or billions) of a particular region of DNA is called Polymerase Chain Reaction(PCR). It requires a primer, DNA helicases, DNA polymerases, etc.,

So, the correct option is ‘ Nucleotide precursors’.

Receptors associated with aortic arch and carotid artery can recognise a change in $CO _{2}$ and $H^+$ concentration and send necessary signals to the rhythm centre (medulla oblongata) that controls the rate of breathing.

Ringworm is a skin infection which is characterized by the formation of a ring-like a pattern in the rash. It is caused by the fungal species name Tenia. The ringworm infection can occur in different parts of the body like feet, armpits, scalp, thighs, groin, etc.

Claviceps is an ergot fungus that grows on the ears of rye and related cereal and forage plants.
Consumption of grains or seeds contaminated with the survival structure of this fungus the ergot sclerotium, can cause ergotism in humans and mammals.
So, the correct answer is 'Ergotism'
