Chapter 6c:Eukaryotic Chromosomes, part 2: DNA compaction in chromosomes
(2 pts.)
What is your name?______________________________
1a. (2
pts.) About how many bp (roughly)
of DNA is wrapped around the nucleosome core particle?
(I'm looking for the fragment left after "heavy digestion" in
Figure 6.8 of page 231!)
1b. (2
pts.) Name the 5 levels of DNA compaction
in chromosomes.
(see Figure 6.10 on page 232)
2. (4
pts.) What would the consequences
be of the following sequence, in terms of chromosome condensation?
