Certain genes have apparently unusual inheritance patterns. For instance, in the mouse autosomal gene H19, only the copy inherited from the mouse's mother is expressed. Conversely, in the mouse autosomal gene Igf2, only the copy inherited from the mouse's father is expressed. The consequence of this is that imprinted genes are expressed as if they were present in only one copy, even though there are two copies of each of these genes in each cell. What process or processes are responsible for this phenomenon

In prokaryotes, genes can exist as operons that are transcribed into a polycistronic mRNA, containing multiple genes in a single transcript. In eukaryotes, transcripts exist only as monocistronic mRNA containing a single gene. What fundamental genetic difference is responsible for this distinction?

Assume liver and kidney tissues from the same mouse each contain about 10,000 species of cytosolic mRNA, but only about 25% of these are common to the two tissues.

Suggest an experimental approach that might be used to establish that some of the mRNA molecules are common to both tissues, but others are not.

Select all that apply.

-Southern blotting could be used to measure the fraction of common mRNA molecules.

-Common mRNA could be measured using the yeast two-hybrid system.

-Northern blotting could be used to measure the fraction of common mRNA molecules.

-DNA microarrays could be used to compare the mRNAs produced in the two tissues.

-Common mRNA could be measured using nuclear run-on transcription.

A) a threadlike pseudopod

B) a pigmented central vacuole, surrounded by a tonoplast
