Some genes are important enough to be called "molecular switch" or "master" genes. What is the purpose of these genes?
trapecia [35]

Answer:

Genes called "molecular switch" or master genes have the purpose of control when other genes are expressed (option A).

Explanation:

Master gene is so named because it has the function of controlling the behavior of other genes, organizing their functions and regulating when they can be expressed.

The name of molecular switch is synonymous with the master gene, since its activation determines the genetic regulation necessary to establish cell differentiation and even the determination of the sex of some species.

The other options are not correct because:

<em>     B. Master genes do not </em><u><em>determine the organization of the genome</em></u><em> .</em>

<em>     C. </em><u><em>Regulation of cell metabolism</em></u><em> depends of substances as hormones and enzymes. </em>

<em>     D. </em><u><em>The rate of translation</em></u><em> does not depend on the activity of master genes.</em>

leva [86]

The question is incomplete. Th ecomplete question is as following:

All of the following protect the skin and mucous membranes from infection EXCEPT  

A) multiple layers of cells.

B) tears.

C) saliva.

D) HCl.

E) the "ciliary escalator."

Answer: D) HCl.

Explanation:

  • The epidermis, the outer layer of the skin provides waterproofing and serves as a barrier to infection and other laers also sustain any type of injury.  
  • Tears wash out foreign bodies which enter the eye. In addition, tears contain a substance called lysozyme which has an antibacterial function and works to prevent microbial invasion and infection.  
  • Saliva protects against infection, especially via the innate immune system. This mechanism is an important first-line protection against bacterial and viral infection
  • The mucociliar escalator is within the conducting airways and is composed of mucus and cilia that transfer the mucus up and out of the lungs where it can be removed by coughing or swallowing,

Whereas HCL helps in the digestion process.

Hence, the correct option is D.
