The question is:
What may be observed as a result of the described mutation in an individual?
<span>1) Skin cancer due to UV rays </span>
<span>2) Darker blue pigmentation </span>
<span>3) A lack of alterase for other functions it may serve </span>
<span>4) The release of a different pigment color
The correct answer is B.
In this theoretical molecular cascade, we have three key parts, the blue2 gene, the blue2 operator and the enzyme alterase.
The enzyme alterase stops the expression of the blue2 gene by binding to its operator, and therefore the blue pigment protein.
The blue2 operator has a specific binding spot for alterase. If this binding spot is changed due to a conformational change, the alterase would not be able to bind to the operator and the blue2 gene could express undisturbedly, resulting in increased concentration of the blue pigment protein.</span>
The different barriers that you have to go through are the different organs of the immune system. These are the lymphoid organs, thymus, and bone marrow. The secondary wall that you have to go through are the lymphatic tissues which include the lymph nodes, adenoids, skin, liver, tonsils, spleen, and the lymph vessels.
At all times, these systems work hand-in-hand so that the body can protect itself in order for it to survive

<span>Activists felt that their calls for a single-payer system were not being taken seriously and the need for hearings on the subject were being downplayed. This is justified because, at the very least, there could have been debate on the subject instead of a complete shutting-out of their wishes. Sen. Baucus could have, at the very least, called for a committee hearing on the subject and questioned advocates of the concept about the pros and cons of a single-payer system, instead of completely downplaying the idea out-of-hand. This could have led to an increase in interest in the idea and maybe even bringing some of the ideas into the current health-care system.</span>
