If you wanted to design an artificial hormone who's action on a target cell required the least amount of interaction with that c
vitfil [10]

Answer:

The water soluble hormones affect the target cells with least amount of interaction.

Explanation:

Hormones are the chemical messengers. These are the substances secreted by the endocrine glands. The hormones are secreted directly into the bloodstream and are carried to the target cells within the blood only.  

Based on their structure, hormones are water-soluble or lipid-soluble. The lipid-soluble hormones are steroid hormones and thyroid hormones. These hormones can easily pass through the lipid bilayer of the cell membrane of the target cell. Therefore, the lipid-soluble hormones have intracellular receptors that are present in either cytoplasm or the nucleus of the target cells.  

On the other hand, the water-soluble hormones can not pass through the lipid bilayer of the target cells. Therefore, these hormones have extracellular receptors on the surface of the target cells. Binding of the water-soluble hormones to their cell surface receptors triggers the production of the intracellular second messengers that finally carry the signal to the target protein or any other target molecule.

<u>Therefore, a water-soluble hormone exhibits the least amount of interaction with the target cell. Amine hormones such as epinephrine and melatonin, peptide hormones such as oxytocin are some examples of the water-soluble hormones.  </u>

Which of the following is a reason why sticky end producing restriction enzymes are preferred compared to blunt end ones?
anyanavicka [17]

Answer:

D) Because sticky ends can be temporarily held together by hydrogen bonding between the two strands.

Explanation:

Restriction enzymes cut the DNA at specific restriction sites and by the mechanism of action they can form two types of ends:

  • sticky ends-single-stranded overhangs are formed
  • blunt ends-without overhangs.

The main advantage of sticky ends (their overhangs) is that they can complementary bind to another overhand formed by the same restriction enzyme. So, for example in cloning, if the DNA of interest and plasmid vector are cut with the same restriction enzyme, that  forms sticky ends, fragment of DNA will fit into a bacterial plasmid in one direction.

On the other hand, blunt ends can be inserted into vector in both directions: head-to-tail or tail-to-head.
