Dna damage can occur as a result of exposure to chemicals or ultraviolet radiation. This is what happens during nucleotide excision repair of damaged dna. A multienzyme complex crosses the DNA in search of distortions in the double helix, once located, the phosphate skeleton of the affected chain is cut on both sides of the altered region, a helicase eliminates the oligonucleotide resulting from digestion, the "Gap" "is filled with a DNA polymerase and a ligase.

Explanation:
In a hen house, the length of daylight is prolonged by using indoor lighting. the stimulus for egg laying is
(a) food
(b) warmth
(c) light
(d) amount of water.
The correct answer is option (c) light.
Light is found to have a significant effect on egg laying by hens in the hen houses or poultry. Photoperiod is the length of the time within a day to which the hens are exposed to sunlight or artificial source of light. Egg production is reduced if the light intensity and duration is reduced. A peak production of hens is observed with the photoperiod is lengthened or a longer photoperiod.
Natural day light exposure to hens results in the production of not more than 40 eggs. Whereas, a prolonged day light of 12- 14 hours by indoor lighting increases the number of eggs layed to around 60 eggs. Thus, the stimulus for egg laying is the light.
Thus, In a hen house, if the length of daylight is prolonged by using indoor lighting, the stimulus for egg laying is light.
The answer is the plant growth, because the dependent variable is what responds to the independent variable.
None of the above i believe... if not it’s specialization
