To Maximize the Number of Thymine Dimer Mutations Following UV

question 58

Multiple Choice

To maximize the number of thymine dimer mutations following UV exposure, should you keep a plate of fungal cells in the dark, in the light, or does it matter at all?

• A) The dark-light will activate the photorepair systems that can break thymine dimers induced by UV light.
• B) The light-it's important to keep on producing the thymine dimers by keeping the plate exposed to light as much as possible.
• C) It's best to alternate light and dark every hour to increase the chances that thymine dimers will form in the fungal cells, but still keep the photorepair systems from correcting them as they are formed.
• D) It doesn't matter-fungal cells don't possess the enzymes needed for photorepair of thymine dimers. They're only in prokaryotes.

Definitions:

Average Variable Cost

The variable cost (costs that change with production volume) divided by the quantity of output produced.

Marginal Cost

The increase or decrease in the total cost incurred by producing one additional unit of a product or service.

Total Variable Costs

The sum of expenses that vary directly with the level of output production.

Average Total Cost

The per unit cost of production, calculated by dividing total cost by the total quantity of output produced.
