What is the difference between euchromatin and heterochromatin?

Consider the figure beow, which depicts chromatin within the neucleus of a eukaryotic cell. nucleus O The letter A indicates regions of a single chromosome which are not expressed, and the letter B indicates regions of a single chromosome which are expressed. O Both answer choice A and answer choice B are correct. The letter A indicates regions of a single chromosome which are condensed and attached to the nuclear lamina, and the letter B indicates regions of a single chromosome which are partially decondensed. O Answer choices A, B and C are all correct. O The letter A represents repressed TADS, and the letter B represents active TADS.

How many nucleosomes form the “width” of the 300 Angstrom fiber, in chromatin packaging?

What is the function of euchromatin?

What are the two types of heterochromatin?

Describe constitutive heterochromatin and facultative heterochromatin. Based upon this information, what would you predict would happen during the embryonic development of an organism if some regions of facultative heterochromatin were changed to constitutive regions? Answer in detail.

Which of the following make up a core nucleosome structure?   A)  about 147 bp of DNA D)  A tetramer of histone proteins C)  H1 histone E)  Answers A and B are correct B)  an octamer of histone proteins

6) There is clear evidence that chromatin state is directly related to the ability of proteins to initiate gene transcription. Compare and contrast euchromatin to heterochromatin in the context of transcription. Specifically comment on DNA and protein interactions.

What is the molecular basis of genetic information?   base sequences   sugar-phosphate backbone   chromatin supercoiling   phospholipids

What does the nucleosome accomplish?
