Answer:
Animals, plants, and bacterias
Explanation:
<span>Cofactors are non protein chemical compounds. During DNA synthesis all DNA polymerases all share a two-metal ion-catalyzed polymerase mechanism. One of the metal ions attacks the primer hydroxly group, the second stabilizes the oxygen's negative charge. Magnesium ions are key to enzymatic reactions as they can generate magnesium-substrate scaffolds to which enzymes bond.</span>
Answer:
two (a pair)
Explanation:
Centrioles are the pair of hollow cylinders that are located near the nucleus in the cytoplasm in a non-dividing cell. Two centrioles together make a centrosome. Centriole duplication occurs before cell division as the duplicated centrioles take part in the formation of the spindle apparatus. However, cytokinesis distributes one pair of centrioles to each daughter cell. Therefore, after cytokinesis, two centrioles are present in each daughter cell.
False; Alpha particles rarely penetrate human skin, but beta and gamma particles can and are considered very dangerous.
