Gala2k [10]2 years ago

Answer:

Yeast cells are eukaryotic and modify proteins similarly to human cells

Explanation:

  • Bacterial cells are prokaryotic and are different in structure to human cells, thus the way in which they metabolize and express proteins will be different.
  • Yeast cells are similar to human cells and diploids can be made from yeast.
  • Yeast cells are eukaryotic and thus have mostly the same cell machinery and structure that human cells have and this is a more accurate vector to test expression of human proteins.

Lactose when digested, it is hydrolyzed by lactase into its monomers, which are then absorbed by blood. Following are test resul
kap26 [50]

Answer: Based on the information, the person DOES NOT have lactose intolerance because glucose levels significantly increases in normal individuals after a lactose rich meal.

Explanation:

Lactose is a disaccharide carbohydrate which when taken (found mostly in diary products) is hydrolyzed by lactase into its monomers, which are then absorbed into the blood. The hydrolysis of lactose gives glucose and galactose which is carried out by the digestive enzyme lactase. Deficiency of the lactase enzyme gives rise to a disorder known as LACTOSE INTOLERANCE.

The diagnosis of lactose intolerance or lactase deficiency can be confirmed by measuring the plasma glucose concentrations, as in glucose tolerance test, after giving an oral load of lactose rich solution. If the disaccharide (lactose) cannot be hydrolysed, the constituent monosaccharides cannot be absorbed and the concentrations of plasma glucose rise VERY little.

But the fasting blood glucose done after 2 hours of drinking a lactose rich solution showed a typical rise in blood glucose levels which were 80, 90, 100, 110 and 120 mg/ dL tested for every 30 minutes. This indicates that the individual does not have lactose intolerance because the glucose gotten from hydrolysed lactose was absorbed and cause a significant rise in blood levels.

The leucine zipper motif functions to A. mediate the physical association of two polypeptides. B. anchor transcriptional activat
Vera_Pavlovna [14]

Answer:

Option A (mediate...........polypeptides) would be the appropriate choice.

Explanation:

  • That's only because the leucine zipper symbol consisting of such a leucine remnant anywhere certain 7th point and has an α helical attachment.
  • Maybe the leucine including its zipper between one protein dimples again from α-helix as well as interdigit this same leucine including its iterator of some other antibody.

Some other possibilities in question are not connected to something like the situation in question So that is the correct approach.

Valentin [98]

Multicellular organisms can be much larger and more complex. This is because the cells of the organism have specialised into many different types of cells such as nerve cells, blood cells, muscle cells all performing different functions
