Answer:

d) 5'-UGUGUGUGUGUGUGUG...-3'

Explanation:

A UG dinucleotide is when UG is repeated.

mRNAs are transcribed and translated as a 5' to 3' molecule. Therefore, the direction should be 5' - 3'.

For the mRNA to be in frame, it must start with UG. The only option that runs 5' - 3' and is in frame for a UG dinucleotide is d.

The lactose-digesting bacteria like to grow on milk agar .Bacillus cereus growth and survival were examined during the production of cheese of the Gouda variety. Approximately 102 B. cereus spores per milliliter of cheese milk were intentionally added to pasteurized milk before it was used to make the cheese in the pilot plant.

"milk agar," in which 2% nonfat powdered milk is added to the agar base. lactose-digesting bacteria like to grow on milk agar. Surface plating on B. cereus selective medium was used to count B. cereus, while lactic acid bacteria were counted on lactic agar and MRS agar (de Man-Rogosa-Sharpe). Samples of the milk before renneting, the curd at cutting, the half-whey removal, the final whey removal, the hooping of the curd, the cheese after pressing, the cheese after brining, after one week, after two weeks, after four weeks, and after six weeks were all taken for microbiological analysis. The growth of lactic acid bacteria during cheese production was unaffected by B. cereus.

What does the frequency do?
Elina [12.6K]
Frequency describes the number of waves that pass a fixed place in a given amount of time. So if the time it takes for a wave to pass is is 1/2 second, the frequency is 2 per second. If it takes 1/100 of an hour, the frequency is 100 per hour.
