Answer:
GGATCC
CCTAGG.
Explanation:
Pallindromic sequence may be defined as the sequence of the nucleotides that reads in the certain direction on which the strand reads and they are complementary to each other.
These sequences when read in 5' to 3' direction, the sequence is similar from 3' to 5' direction as well. The sequence GGATCC when reads from the oppposite direction results in the same sequence CCTAGG. Hence, these are pallindromic sequences.
Thus, the correct answer is option (d).
The Cretaceous Period was the last and longest period of the Mesozoic Era. It lasted 79 million years.
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>
Well, if the big fish are predators, then more food for them and their population would increase greatly. If the big fish and small fish have the same type of food, then that means that the big fish, hypothetically, would have millions of new contenders for their food source. That means that it's very likely that many of those big fish would die out.
