Answer:
mRNA
Explanation:
poly-deoxythymidine (poly-dT) beads binds to polyadenylated (poly (A) molecules with high affinity because Thymidine base pairs with the Adenine of the poly(A) chain.
Since messenger RNA (mRNA) is polyadenylated after transcription in contrast to other RNA species, this method is more suitable for mRNA purification.
Answer;
B. Both primary and secondary succession involve ecosystems recovering from a disruptive event.
Explanation;
-Primary succession occurs following an opening of a pristine habitat, for example, a lava flow, an area left from retreated glacier, or abandoned strip mine. In contrast, secondary succession is a response to a disturbance, for example, forest fire, tsunami, flood, or an abandoned field.
-Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. Secondary succession follows a major disturbance, such as a fire or a flood.
