Snuppy, a male Afghan hound, was created by transferring the nucleus from an ear cell of the male Afghan, Tai, into an enucleate
d egg from a donor. The embryo was transplanted into a surrogate mother to develop to term. Which of the following animals would be a genetic match for Snuppy if nuclear DNA were tested? A) Tai
B) the egg donor
C) the surrogate
D) both Tai and the egg donor
E) both Tai and the surrogate
According to the given information, nucleus from the ear cells of the male "Tai" was inserted into the egg cell from a donor. The nucleus of the egg cell was removed before transferring the nucleus from Tai. Therefore, the egg cell contained the nucleus of the ear cell from "Tai". The embryo developed from this egg would have the nuclear DNA from Tai as the nuclear DNA from the egg donor was removed during enucleation. The embryo would be genetically similar to the male Afghan "Tai" who served as a donor of the nuclear DNA.
ATP provides energy coupling between exergonic and endergonic reactions.
Explanation:
Adenosine triphosphate is an important molecule found in the cells and its role is to transport energy that is necessary for the cell or metabolic activities. These activities include muscle contraction and nerve impulse propagation.
The ATP provides energy to both the energy consumption actions and energy-releasing reactions and thus needs a small amount of input of energy. The chemical bonds on breaking provide energy for cells to work.
Lapilli: Rock fragments between 2 and 64 mm (0.08-2.5 in) in diameter that were ejected from a volcano during an explosive eruption are called lapilli.
