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 answer is cyanobacteria.
Answer: The answer is c because Molecules are polar.
Spasticity results from the sustained muscle contractions due to an increase in excitatory influences or a decrease in inhibitory influences within the central nervous system. In this case, to relieve spasticity the nurse should anticipate Dantrolene medication. Dantrolene acts within skeletal muscles by interfering with the release of calcium from the muscle fibres.
The answer is <span>the number of DNA mutations in an organism is measured over time to determine how long it will take for a new species to evolve.</span>
