(Problem 3) Which of the following is NOT a molecular mechanism
that alters chromatin structure and is responsible for many
epigenetic phenotypes? |
|
|
Chemical modifications of histone proteins |
|
Changes in DNA methylation |
|
Cytoplasmic inheritance of noncoding DNA |
|
RNA molecules that affect chromatin structure and gene
expression
| Which of the following is NOT an epigenetic mechanism? |
|
|
Long noncoding RNAs |
|
Random mutation |
|
X inactivation |
|
DNA methylation |
|
Histone modifications
| Problem 19) What is the epigenome? |
|
|
It is the overall pattern of chromatin modifications possessed
by each individual organism. |
|
It is the sequence of long noncoding RNAs that coat the
chromosomes of the cells found in each individual organism. |
|
It is the overall pattern of nucleotide differences between
alleles found in each individual organism. |
|
It is the pattern of genomic rearrangements that have occurred
along the evolutionary history of related groups of organisms. |
|
It is the diversity of proteins expressed by any given cell of
each individual organism.
|
What is the molecular basis of the epigenetic effect of royal
jelly? |
|
|
Inhibits Dnmt3, causes less histone methylation |
|
Inhibits Hdac3, causes less histone acetylation |
|
Inhibits Dnmt3, causes more DNA methylation |
|
Inhibits Dnmt3, causes less DNA methylation |
|
Inhibits Dnmt3, causes more histone methylation |
