Chapter 10: Problem 15

Compare heterochromatin and euchromatin. What are the differences between them?

Short Answer

Expert verified
Heterochromatin is densely packed and generally inactive, while euchromatin is lightly packed and typically active for transcription. Heterochromatin stains more intensely due to its structure.

Step by step solution

01

Define Heterochromatin

Heterochromatin is a densely packed form of DNA. Its tight configuration inhibits the transcription process as the genes in this region are generally inactive.
02

Define Euchromatin

Euchromatin is a lightly packed form of DNA. It is in this region where most of the transcription activity takes place because the genes are active and accessible.
03

Contrast Heterochromatin and Euchromatin

The primary differences between heterochromatin and euchromatin lie in their structure and function. Heterochromatin is highly condensed and transcriptionally silent, while euchromatin is less condensed and transcriptionally active. Another difference lies in their staining properties, with heterochromatin staining more intensely than euchromatin because of its tightly packed form.

How are two topoisomers different from each other? How are they the same?

Beginning with the \(\mathrm{G}_{1}\) phase of the cell cycle, describe the level of compaction of the eukaryotic chromosome. How does the level of compaction change as the cell progresses through the cell cycle? Why is it necessary to further compact the chromatin during mitosis?

Take two pieces of string that are approximately 10 inches long, and create a double helix by wrapping them around each other to make 10 complete turns. Tape one end of the strings to a table, and now twist the strings three times \(\left(360^{\circ}\right.\) each time) in a righthanded direction. Note: As you are looking down at the strings from above, a right-handed twist is in the clockwise direction. A. Did the three turns create more or fewer turns in your double helix? How many turns does your double helix have after you twisted it? B. Is your double helix right-handed or left-handed? Explain your answer. C. Did the three turns create any supercoils? D. If you had coated your double helix with rubber cement and allowed the cement to dry before making the three additional right-handed turns, would the rubber cement make it more or less likely for the three turns to create supercoiling? Would a pair of cemented strings be more or less like a real DNA double helix than an uncemented pair of strings? Explain your answer.

Compare the structure and cell localization of chromosomes during interphase and \(\mathrm{M}\) phase.
