Answer:
Epithelial cells are tightly packed, and this lets them act as barriers to the movement of fluids and potentially harmful microbes. Often, the cells are joined by specialized junctions that hold them tightly together to reduce leaks.
Explanation:
Answer:
2. presence of plasma membrane 3. lack of a nuclear envelope
Explanation:
Both archaeans and bacteria are prokaryotes. The prokaryotic organisms lack the well-defined nucleus and membrane-bound organelles. These organisms have their genetic material present in the cytoplasm itself.
Both archaeans and bacteria have a plasma membrane around their cells. The presence of plasma membrane around cytoplasm is exhibited by all the living beings including all the prokaryotes. Plasma membrane in archaeans and bacteria has the same basic structure. It has two layers of phospholipids in which proteins are embedded.
Answer:
Prokayotes may be defined as the organisms that lacks the nucleus and the membrane bound cell organelle. Eukaryotes have the well defined nucleus and contains the membrane bound cell organelle.
The evolutionary advantage that has been noticed in the eukaryotic cells is the compartmentalization of the cell. The cell compartmentalization separates the cell organelle into the specialized functions. This division of labor increases the efficiency of the cell and regulates the evolution of the complex multi cellular organism.
Answer:C
Explanation:
During termination of transcription a section of DNA contains about 20 basepair GC nucleotides. This GC rich sequence that marks the end of a gene during transcription.
In the Rho-independent transcription termination mechanisms, the formation hairpin rich in GC nucleotides causes RNA polymerase to stall,
It is difficult for RNA polymerase can to work pass through GC rich hairpin, because GC basepair is made of 3 hydrogen bonds.
This causes the RNA polymerase to stall
