Normal gene order for a particular chromosome is ABC*DEF (where
* is the centromere). An inversion changed the gene order to
AD*CBEF. If an individual is heterozygous for the inversion (has
one normal chromosome, and one with the inversion), show how the
two chromosomes will pair in meiosis. Then show the chromosomes
that will result if crossing over occurs in the inversion. Please

Which statements about the modification of chromatin structure in eukaryotes are true?
DNA is not transcribed when chromatin is packaged tightly in a condensed form
Methylation of histone tails in chromatin can promote condensation of the chromatin

6. During mitosis cells use changes in the chromosome apparatus
to accurately separate their chromatid pairs between two cells.
A. Please explain (and considering making a diagram) of how the
spindle microtubules change across the process of mitosis. Please
explain how chromosome attached microtubules change across mitosis
and add those to your drawing.
B. Please explain where and how changes in polymerization of
microtubules drive these changes and how motor proteins function in
C. Please EXPLAIN HOW cells...
There is a gene in eukaryotes under the control of a transcriptional activator that ultimately regulates chromatin structure. This transcription factor requires dimerization to function. Given your understanding of how transcription factors work, list four different mutations that could disrupt the regulation of this gene and the functional consequences of these individ ual mutations. Consider both cis- and trans- acting elements and different protein domains.
