If you were given a sample of chromosomal DNA and asked to determine if it is bacterial or eukaryotic, what experiment would you perform, and what would be your expected results?
See AnswerQ: Consider how histone proteins bind to DNA and then explain why a
Consider how histone proteins bind to DNA and then explain why a high salt concentration can remove histones from DNA (as shown in Figure 10.18b). From Figure 10.18b:
See AnswerQ: Discuss why you think the ribosomes need to contain so many proteins
Discuss why you think the ribosomes need to contain so many proteins and rRNA molecules. Does it seem like a waste of cellular energy to make such a large structure so that translation can occur?
