olga nikolaevna [1]

Answer:

The correct answer is "both Cdc6 and Cdt1"

Explanation:

The replisome is a complex molecular system that allows for the replication of DNA in yeast. There are multiple genes that participate in the replisome function, however if a researcher finds out that a yeast strain fails to properly form replisomes it is very likely that the genes that might be mutated are both Cdc6 and Cdt1. Cdc6 and ORC are the genes that send the signal to the yeast to start the replisome formation, and Cdt1 is a DNA replication factor that if it is mutated it could cause that yeast is not able to form the replisome.

Marat540 [252]

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.

With reference to the induced fit model, describe how the tertiary structure of a named enzyme facilitates its function as a bio
Olenka [21]

The induced-fit model includes the change in the conformational site of the substrate and enzyme. It is done till the enzyme completely binds the substrate. This will then activates the enzyme to perform its work.

<h3>What is induced fit theory?</h3>

Induced fit theory or model suggest that the activation site of enzymes and the binding site of substrates undergo some conformational changes to fit into each other.

This binding results in activation of the enzyme and as the enzyme has a three-dimensional tertiary structure, this would help it to get fitted into the substrate.

Thus, with reference to the induced fit model tertiary structure of enzyme facilitates its function as a biological catalyst.
