Arguably, the way prokaryotic operons are structured has evolutionary advantages. Based on our discussions in class, briefly des
Naddik [55]

Answer:

Advantage of gene expression in prokaryotes is it occurs faster than in eukaryotes because  transcription and translation occur simultaneously in the cytoplasm, and regulation occurs at the transcriptional level. Whereas disadvantage of gene expression in prokaryotes is that there is no post translational modification and low expression of genes.

Explanation:

Prokaryotic organisms are single-celled organisms that lack a cell nucleus, and their DNA therefore floats freely in the cell cytoplasm. To synthesize a protein, the processes of transcription and translation occur almost simultaneously. When the resulting protein is no longer needed, transcription stops. As a result, the primary method to control what type of protein and how much of each protein is expressed in a prokaryotic cell is the regulation of DNA transcription. All of the subsequent steps occur automatically. When more protein is required, more transcription occurs. Therefore, in prokaryotic cells, the control of gene expression is mostly at the transcriptional level. whereas in eukaryotes, the DNA is contained inside the cell’s nucleus and there it is transcribed into RNA. The newly synthesized RNA is then transported out of the nucleus into the cytoplasm, where ribosomes translate the RNA into protein. The processes of transcription and translation are physically separated by the nuclear membrane; transcription occurs only within the nucleus, and translation occurs only outside the nucleus in the cytoplasm.

makvit [3.9K]

Answer:

B; Not work

Virty [35]

Answer:

The third sentence is not correct. The correct statement would be as follows:

because the contents of the lumen of ER (or any other compartment) in the secretory or endocytic pathways never mix with the cytosol, Proteins that enter these pathways is never imported again.

Explanation:

During mitosis, specifically during prophase, when the nuclear envelope breaks down, or in other words, retracts from the chromatin, its content that is the membrane protein intermix with the ER membrane protein. However its content will always remain separated from that of the cytosol because of the presence of an intact membrane.

What happens to the membrane of a vesicle after exocytosis?
morpeh [17]

Answer:

It fuses with and becomes part of the plasma membrane.

Explanation:

Exocytosis -

Exocytosis is the process of expelling out the substances from the cell . It also helps in the cell transport and cell signalling process .

In this process a large amount of molecule are released and making it a form of the bulk transport .

In this process , the secretory vesicles are then carried to membrane of the cell and then their contents are secreted into the extracellular environment .
