In an HIV-Infected Cell Producing HIV Virus Particles, the Viral

question 58

Multiple Choice

In an HIV-infected cell producing HIV virus particles, the viral glycoprotein is expressed on the plasma membrane. How do the viral glycoproteins get to the plasma membrane?

• A) They are synthesized on ribosomes on the plasma membrane.
• B) They are synthesized by ribosomes in the rough ER, and arrive at the plasma membrane in the membrane of secretory vesicles.
• C) They are synthesized on free cytoplasmic ribosomes, and then inserted into the plasma membrane.
• D) They are synthesized by ribosomes in the rough ER, secreted from the cell, and inserted into the plasma membrane from the outside.
• E) They are synthesized by ribosomes on the HIV viral membrane, which fuses with the plasma membrane from inside the cell.

Embryonic Differentiation

Embryonic differentiation is the process during embryonic development in which unspecialized stem cells give rise to specialized cells, forming various tissues and organs.

Apical Meristems

Regions at the tips of roots and shoots in plants where cells actively divide, allowing for elongation and growth.

Dermal Tissues

Plant tissues that make up the outer layer of a plant, providing protection and aiding in gas exchange.

Vascular Tissues

The complex tissues in plants responsible for conducting water, nutrients, and food throughout the organism, consisting mainly of xylem and phloem.
