How far back can radiometric dating go? C (the […]
What are the advantages of an Endospore?
What are the advantages of an Endospore? It allows the bacterium to produce a dormant and highly resistant cell to preserve the cell’s genetic material in times of extreme stress. Endospores can survive environmental assaults that would normally kill the bacterium. Why are endospores so hard to kill? DPA has the ability to cross-link with […]
