Answer:

live attenuated vaccine

Explanation:

The correct answer would be a <u>live attenuated vaccine.</u>

<em>Vaccines are made from weakened/inactivated pathogens or their toxins and when they are administered to the body, they stimulate the body's immune system to produce antibodies that tend to persist and tackle any future invasion of the body by the pathogen.</em>

Vaccines can be an inactivated ones if they are made from inactivated pathogens, <u>they can be live attenuated if they are made from a weakened or attenuated version of the pathogen</u>, or toxoid vaccine if they are made from toxins of the pathogen. Other forms of vaccines include mRNA vaccines, conjugate vaccines, and viral vector vaccines.

The difference between prokaryotic and eukaryotic gene regulation
sleet_krkn [62]

Answer:

READ THIS

Explanation:

To understand how gene expression is regulated, we must first understand how a gene codes for a functional protein in a cell. The process occurs in both prokaryotic and eukaryotic cells, just in slightly different manners.

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.

Eukaryotic cells, in contrast, have intracellular organelles that add to their complexity. In eukaryotic cells, 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. The regulation of gene expression can occur at all stages of the process (Figure 1). Regulation may occur when the DNA is uncoiled and loosened from nucleosomes to bind transcription factors (epigenetic level), when the RNA is transcribed (transcriptional level), when the RNA is processed and exported to the cytoplasm after it is transcribed (post-transcriptional level), when the RNA is translated into protein (translational level), or after the protein has been made (post-translational level).
