What are the four factors that drive the evolution of new
adaptations? Describe each. Give a detailed example of each,
including organism and genes and how these changed.
Describe the evolution of the virtual organization. What are the
pros and cons associated with this design? Provide examples of
three technological devices/concepts that have had the greatest
impact on virtual organizations. Respond to at least two of your
peers for this posting.
Q1.
a. Dynamic changes in chromatin organization and the management
of individual linear chromosomes mark key
activities of the different stages of the eukaryotic cell cycle and
cellular reproduction. Describe how chromatin
amount and structure vary throughout the cell cycle, and how
management of individual chromosomes varies
between mitosis and meiosis to produce the different outcomes of
these processes.
b. RNA is often considered to be a more versatile macromolecule
than DNA. Discuss the different roles of RNA
in eukaryotes.
Chemical modifications of histone tails are often made in
chromatin to change the amount of chromatin compaction. Name three
chemical modifications that have been observed by scientists to be
on histone tails in chromatin. the modifications that you listed
and discuss whether that modification is associated with closed or
open chromatin.
