QUESTIONS AND CORRECT
DETAILED ANSWERS (VERIFIED
ANSWERS) ALREADY GRADED A+
Which of the following is not true. - Answer-A cell can temporarily decondense its
chromatin to silence genes during
differentiation
Which of the following best describes the mechanism by which chromatin-remodeling
complexes "loosen" the DNA wrapped around the core histones - Answer-they use
energy derived from ATP hydrolysis to change the relative position of the DNA and core
histone octamer
When there is a well-established segment of heterochromatin on an interphase
chromosome, there is usually a special barrier sequence that prevents the
heterochromatin from expanding along the entire chromosome. Gene A, which is
normally expressed, has been moved by DNA recombination near an area of
heterochromatin. None of the daughter cells produced after this recombination event
express gene A, even though its DNA sequence is unchanged. What is the best way to
describe what has happened to the function of gene A in these cells - Answer-
epigenetic inheritance
The chromosomes we typically see in images are isolated from mitotic cells. These
mitotic chromosomes are in the most highly condensed form. Interphase cells contain
chromosomes that are less densely packed and -
Answer-occupy discrete territories in the nucleus
Which of the following is not a chemical modification commonly found on core histone
N-terminal tails - Answer-hydroxylation
Which of the following is true vasued on amino acids - Answer-Nonpolar amino acids
tend to be found in the interior of proteins
A newly synthesized protein generally folds up into a _(42)_ conformation. All the
information required
to determine a protein's conformation is contained in its amino acid _(43)_. On being
heated, a
protein molecule will become _(44)_ as a result of breakage of _(45)_ bonds. On
removal of urea, an
unfolded protein can become _(46)_. The final folded conformation adopted by a protein
, is that of
_(47)_ energy - Answer-42: stable
43:Sequence
44: denature
45: non covalent
