The type of control is described by the response of the operon when no regulatory protein is extant. In the case of negative regulator, the genes in the operon are distinct unless they are switched off by a repressor protein. Therefore the operon will be turned on essential (the genes will be prcise) when the repressor in inactived. In the case of positive control, the genes are distinct only when an active regulator protein, an activator, is present, Thus the operon will be turned off when the positive regulatory protein is missing or inactivated.

Describe how you would use the yeast-two-hybrid technique to find the proteins that interact with a liver-specific receptor prot
ollegr [7]

Answer:

Yeast-two-hybrid technique is one of the most important molecular technique that can be used to study the interactions at the molecular level. The interactions between the protein and DNA-protein  interaction can be studied by this technique.

If the individual wants to study the liver liver-specific receptor protein then yeast-two-hybrid technique can be applied. The interested protein that can acts as prey and bait proteins must be covalently linked with the other third protein known as the reporter protein.  Then the activity of the reporter protein is studied with the interactions of the prey and bait protein.

iren2701 [21]

Answer & explanation:

This acidity in our stomach is advantageous because it kills most bacteria and creates the ideal environment for the enzymes pepsin and gastric lipase to digest food.

The pH corresponds to the hydrogen potential of a solution, this potential can be classified as acid, basic or neutral.

Respuesta y explicación:

Esta acidez en nuestro estómago es ventajosa porque mata a la mayoría de las bacterias y crea el ambiente ideal para que las enzimas pepsina y lipasa gástrica digieran los alimentos.

El pH corresponde al potencial de hidrógeno de una solución, este potencial se puede clasificar como ácido, básico o neutro.

What is the difference between inorganic and organic compounds?
Artemon [7]

Answer:

The main difference is in the presence of a carbon atom; organic compounds will contain a carbon atom (and often a hydrogen atom, to form hydrocarbons), while almost all inorganic compounds do not contain either of those two atoms. Meanwhile, inorganic compounds include the salts, metals, and other elemental compounds.
