Answer:
An immunized person can show false positive results during the test.
Explanation:
BCG (bacille Calmette-Guerin) is the vaccine which is given for tuberculosis. This vaccine is used in many countries in which the chances of spreading Tb is high in children which causes meningitis and miliary disease in children.
In United States, BCG is not recommended because the risk here is very low and the vaccinated person can show false-positive results for the disease which will result in hindering the work of epidemiologists who are tracking how and from where disease spread.
Answer:
See below
Explanation:
A) First of all, it must be considered that HIV has a RNA genome.
The reverse transcriptase is a viral enzyme able to convert a RNA molecule (in this case the RNA would be the viral genome) to DNA. This process is important for two reasons:
* The DNA molecule is more stable than RNA --> Therefore, there is a higher likely that the molecule wouldn't be degradated by the host.
* The viral genome made of DNA will be integrated into the host genome --> To do so, it requires to be DNA instead of RNA
B) The inibitor is able to target the Reverse Transcriptase --> So, the likehood of converting RNA to DNA is lower. In this case, the single RNA molecule is less stable than the DNA and the host can degradate it more easily.
C) In general, the viral will not survive the treatment and, hence, the patient will not suffer from the viral infection
<u>The answer is B. Dominant.</u>
An example of a dominant trait is brown eyes vs blue eyes. If a person carries an allele for both brown eyes and blue eyes, brown eyes will be expressed over the blue eyes because brown eyes are the dominant trait.
