- When cells undergo apoptosis, their DNA becomes fragmented. When the DNA is run out on a gel, the resulting fragments differ in size by a standard amount, about 200 bp, so that the resulting separated DNA has a characteristic "ladder" appearance. Control Staurosporine treatedNucleosomes are the ball-like structures around which the double helix winds. What proteins make up nucleosomes? Group of answer choices hertone histone heterochromatin euchromatinWhen chromatin is treated with non-specific nucleases, what is the length of the resulting pieces of DNA
- If the DNA of chromosome 1 is fully extended, it will exceed the diameter of the nucleus of a cell by about 15,000 times. Therefore, discuss how DNA is packaged into the cell.We seem to know more about the structure of eukaryotic chromosomal DNA than bacterial DNA. Discuss why you think this is so,and list several experimental procedures that have yielded important information concerning the compaction of eukaryoticchromatinDescribe the structure of nucleosome ( please keep it short as much as you can ) .

If the fiber contains about six nucleosomes per 10 nm of length, what is the approximate compaction ratio achieved?A part of a sequenced chromosome has the sequence (on one strand)ATTGCATCCGCGCGTGCGCGCGCGATCCCGTTACTTTCCG. Which part of thissequence is most likely to take up the Z conformation?Address the general properties of the chromatin within the following types of DNA: DNA undergoing active transcription DNA within a mitotic chromosome DNA immediately after passage of the replication fork centromeric DNA
- The picture below depicts electron micrographs of the major levels of chromatin structure. Match each of the listed conditions with the most likely levels of chromatin structure under that condition.Describe heterochromatin and euchromatin when viewed under an electron microscopeEukaryotic DNA is typically organized into two major regions called euchromatin and heterochromatin. Which of the following applies to euchromatin? They are regions of little or no transcription activity. They are regions of highly condensed chromatin. They are regions that are uncoiled and active in transcription. They may refer to regions near the ends of chromosome (telomeres). They refer to regions that contain the centromere.
