Answer:
Phosphorylation within the nuclear export signal interferes with the function of the signal.
Explanation:
In biochemistry, phosphorylation is the addition of a phosphate group (PO4) to a protein or other molecule. Phosphorylation is a major player in protein regulation mechanisms, preventing protein-catalyzed reaction product from accumulating in the body causing problems.
However, in some cases phosphorylation may cause nuclear accumulation of a protein in the nucleus of the cell. An example of this is the protein shown in the question above. In this case, phosphorylation in the nuclear export signal interferes with the signal function, resulting in protein accumulation in the nucleus.
Answer:
Dissecting microscopes are for viewing the surface features of a specimen, and compound microscopes are designed to look through a specimen.
Explanation:
Answer:
A. play a role establishing and maintaining membrane lipid asymmetry
Explanation:
Proteins that move move certain phospholipids between leaflets are transmembrane proteins via "flip-flop" transition have also the possibility to maintain membrane lipid asymmetry. There are few types of such proteins:
- flipases-move lipids from the exterior to the interior side of the membrane, energy required
- flopases-move lipids in reverse comparing to flipases, energy required
- scramblases-no energy required, bidirectional
Because of the action of those proteins, cytosolic side of plasma membrane differs from exoplasmic side (asymmetry).
Answer:
Delegates at the 1992 Fourth World Congress on National Parks and Protected Areas, a decennial international conference that serves as a global forum for setting the agenda for protected areas worldwide, recommended that “protected areas cover at least 10 percent of each biome by the year 2000.”
