Give a scenario where a cell may need to perform a form of endocytosis

1 answer:

6 0

Endocytosis is the process where a cell imports large things into the cell. All forms of endocytosis are active, meaning the cell expends ATP while performing this process. Specifically, a style of endocytosis called phagocytosis involves a cell surrounding the target material with its cell membrane and encloses it while bringing it into the cell. This enclosed membrane bound material then pinches off into a spherical 'vesicle'. An example of this can be a cell importing a protein into its cellular space.

3. Most of the traits expressed in a person's phenotype are determined by Is

Mashutka [201]

Answer: A phenotype is an individual's observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.

Answer:

C.The added epitope disrupts the function of the tagged protein

Explanation:

When an additional sequence is tagged to a protein to use comercial antibodies, there are several reasons why this procedure wouldn't work as expected (note that we're assuming the protein is being expressed but it's not possible to detect it).

For example, the sequence of nucleotide added to codify for the tagged epitope are removed during the RNA processing. In that case, the protein would be expressed without the epitope, so it would be impossible to localize it with the antibodies.

Also, it could be that the new epitope is affecting some way the protein folding, making it not functional. This way, it would be degraded by the cell so it wouldn't be detected.

Another possibility is that the epitope doesn't affects the protein folding nor its function, but during the folding ends up in a conformation that makes it inaccesible for the antibody.

In summary, the way as the possible answers to this question are shown, the correct option seems to be C:<em> The added epitope disrupts the function of the target protein.</em>

How does bacteria cause disease?

lesya692 [45]

Answer:

Bacteria cause disease by secreting or excreting toxins (as in botulism), by producing toxins internally, which are released when the bacteria disintegrate (as in typhoid), or by inducing sensitivity to their antigenic properties (as in tuberculosis).
