question 43

Multiple Choice

In the following schematic graph of a hypothetical set of RNA-seq data, the number of reads is plotted for a region of chromosome containing two genes, from samples obtained from two different tissues. Which gene (X or Y) do you think is more likely a "housekeeping" gene? Which region (1 or 2) within gene Y most likely corresponds to an exon?

• A) Gene X; region 1
• B) Gene X; region 2
• C) Both genes; region 1
• D) Gene Y; region 1
• E) Gene Y; region 2

Definitions:

Optically Active

Describes a substance that has the ability to rotate the plane of polarization of polarized light, a property of chiral molecules.

Distillation

A process used to separate components of a liquid mixture based on differences in their boiling points.

(1S,2S,3R,5S)-Pinanediol

A specific stereochemical configuration of pinanediol, indicating the spatial arrangement of atoms around four chiral centers.

(1S,2R,3R,5R)-Pinanediol

A diol with a specific stereoisomeric configuration, derived from pinene, used in organic synthesis to protect or prepare chiral intermediates.
