Evolution - Answer-Change in the inherited traits in a population of organisms over time. Ecology - Answer-How organisms interact with each other and the environment Natural selection - Answer-A natural process resulting in the evolution of organisms best adapted to the environment. Theory of evolution - Answer-Created by Charles Darwin, organisms pass on their DNA to their offspring; avoiding close relatives for more variety. Microeveolution - Answer-The change in the inherited traits in ...

Describe what would happen to the nuclear export process if RAN GAP was present on both sides of nuclear membrane - Answer Ran would be in the GDP form inside the nucleus. Nuclear export would cease because exportin would not be able to bind RAN-GTP and thus not bind and export cargo. You have identified a sequence that you believe acts as a nuclear localization signal. Describe an experiment that you could do (and the results of that experiment) to show: That your sequence is necessary...
