A research team needs an antibody that binds to a protein of interest so that protein expression can be monitored. They use epit
antiseptic1488 [7]

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>

The correct answers are:

Trematodes are acoelomates that have effective defenses against attack by their hosts' immune system.

Trematodes are flatworms, internal parasites known as flukes. Their life cycle is complex: they sexually reproduce in vertebrates and asexual reproduce in mollusks (mostly snail). The body of flukes is covered with tough tegument that defends them form digestive enzymes of host’s intestine.

Cnidarians are diploblasts that produce complex, capsule-like organelles.

Cnidaria are water organisms with simple structure: two layers of epithelium and a jelly substance between them. The cells of Cnidaria-cnidocytes contain capsule with venom substance in it with protective role.
