Which statement is true about the differentiated cells in an organism? a) all cells begin with the same basic dna but gain additional genes allowing them to differentiate. b) once fertilization occurs, differentiated cells exist because every cell contains different dna c) differentiated cells have the same dna, but they do not activate all parts of their dna d) all cells start with the same dna but lose various non-essential segments of dna during differentiation.

Taq polymerase is an enzyme isolated from the organism thermophilus aquaticus. this organism has been found living in the hot springs of yellowstone national park. this enzyme is used to copy human dna from crime scenes. most reactions are performed at ranges similar to those of the human body; however, what considerations should be made for optimum use of this enzyme? view available hint(s)taq polymerase is an enzyme isolated from the organism thermophilus aquaticus. this organism has been found living in the hot springs of yellowstone national park. this enzyme is used to copy human dna from crime scenes. most reactions are performed at ranges similar to those of the human body; however, what considerations should be made for optimum use of this enzyme? the enzyme will not work on human dna.nothing should be altered.the ph should be decreased.the temperature should be raised.
