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).

katrin2010 [14]

Answer:

An experiment that directly test the hypothesis.

Explanation:

Although there is quite a bit missing from Mary's scientific investigation, the thing that sticks out the most is the fact that Mary is missing an experiment. Mary's hypothesis states that people would fall asleep faster if their room color were to be painted blue. To prove that her hypothesis is true, Mary would need to conduct an experiment to see whether or not she was correct.

Some frogs, when sitting, can absorb all the oxygen they need through the skin.
attashe74 [19]
In order to move you need oxygen and water to form the energy to function. The frog is basically drinking water and doesn’t need to move while doing so. You only need to breath to allow your body to move.
