Hi~~
Human invasive use of outdoor and artificial lightning (AKA light pollution) has made us less able to see the sky and the stars. Light pollution affects our visual abilities to see objects in the sky by altering the colors and contrast of the night-sky, which makes astronomers less able to study the skies.
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>
a. absorbs mostly orange red and blue violet light
I believe the answer is branch gap sorry if I’m wrong
