A chalazion is caused by the oil in the gland becoming too thick to flow out of the gland or the opening of the gland being obstructed. Without anywhere to go, the oil builds up inside the gland and forms a lump in the eyelid.ach of the oil glands, called meibomian glands, produces oil that flows out of the gland into the tears. The oil exits from each gland through a tiny circular opening just behind the eyelashes of the upper and lower lids of both eyes.
Transcription activator-like effector nucleases (TALENs) are artificial restriction enzymes generated by fusing a TAL effector DNA-binding domain to a DNA cleavage domain.Restriction enzymes are enzymes that cut DNA strands at a specific sequence.rom Wikipedia, the free encyclopedia.

Restriction enzymes are enzymes that cut DNA strands at a specific sequence.
Best Answer: C-DNA polymerases-The ending -ase means it is an enzyme and it is named after its function. The function of DNA polymerase would be to make a DNA polymer. A polymer is a large molecule of repeating units. In this case, the individual units are called nucleotides.Source(s): Bio teacher. just now. Report Abuse. Nucleases are used to cut DNA strands. DNA synthases don't exist, but an example of a synthase is ATP synthase which makes the ATP energy molecule. DNA polymerases create polymers (made of multiple subunits) of nucleotides based upon the sequence of a template strand.
