Harlequin ichthyosis, a rare genetic disorder, causes the skin to become thick and scaly. Flaking skin behind the eyelids of individuals with this condition is most likely to damage which structure of the eye

Cornea.

Explanation:

Cornea is the  transparent coat on the colored iris. It helps to focus light on the retina due to its curved nature.Its outer surface is made up of non-keratinized stratified squamous epithelium.It is closest to the eyelid. Therefore, it is more susceptible to damage caused by flaking skin behind the eyelids that occur due to the Harlequin disorder.

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
