A Control Cell That Is Synthesizing a GFP-Labeled Version of Mannosidase

question 191

Multiple Choice

A control cell that is synthesizing a GFP-labeled version of mannosidase II has fluorescence localized in the numerous Golgi complexes of the cell.Normally,this enzyme is synthesized in the endoplasmic reticulum and moves via transport vesicles to the Golgi complex,where it takes up residence.If an experimental cell contains an siRNA that leads to the fluorescence being restricted to the endoplasmic reticulum,with what would the siRNA be likely to interfere?

• A)an mRNA that codes for a protein involved in the transport of the enzyme from the ER to the Golgi complex
• B)an rRNA that synthesizes the enzyme
• C)the synthesis of mannosidase II from its mRNA
• D)an mRNA that codes for a protein involved in the transport of the enzyme from the Golgi complex to the ER
• E)an mRNA that codes for the enzyme

Definitions:

Outer Ear

The outer ear is the external part of the ear, consisting of the pinna and the ear canal, which collects sound waves and directs them into the ear.

Middle Ear

The portion of the ear internal to the eardrum and external to the cochlea, containing three small bones that amplify sound vibrations.

Inner Ear

The innermost part of the ear, containing the cochlea, vestibule, and semicircular canals, which are responsible for sound detection and balance.
