which example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation?
KATRIN_1 [288]

An example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation is option B: replacement of a polar amino acid with another polar amino acid at the protein's surface.

A frequent and well-known example of a missense mutation is the blood condition sickle-cell anemia. Missense mutations exist in the DNA at a single location in sickle-cell anemia patients. A different amino acid is required in this missense mutation, which also alters the overall structure of the protein. Similarly, replacement of a polar amino acid by another polar Ami no acid at the protein's surface is a missense mutation causing change in a single site.

A neutral mutation is one whose fixation is unrelated to natural selection. Therefore, the independence of a mutation's fixation from natural selection can be used to define the selective neutrality of a mutation.

A victim of foreign body airway obstruction become unresponsive. what is your first course of action?
Anna11 [10]
Answer:
Use a head tilt (tilting the head backward) and chin lift to prevent the tongue from obstructing the upper airway, and look for the foreign body that is causing the obstruction.

Explanation.
The backward head tilt and chin lift will prevent the tongue from obstructing airflow.
If the foreign object can be seen and removed, do so. Usually, it is not wise to use the fingers unless the foreign object is visible and accessible.

The next step is to perform CPR because the patient is unresponsive.
