This is true.
An easy way to remember this is that Cis-acting elements are physically linked to a set of structural genes. So promoters and operators are physically linked to the gene they express. They are cis acting because they are on the same strand as the structural gene they control.
On the other side, trans means that they can come from somewhere else and act. A good example of this would be regulatory proteins. These could be expressed somewhere else (or on a different strand) and then bind and affect transcription.
Answer:
It's impossible because there is no place within the cell for it to occur. In eukaryotes, you have two different regions; the nucleus and the cytoplasm. In prokaryotes, however, you lack the nucleus, meaning you only have the cytoplasm. So, as one can see, there is no separate region for post-transcriptional editing of mRNA to occur in prokaryotes.
Answer:
e
Explanation:
ultraviolet rays are most energetic than visible
The correct answer is B. Hypothalamus.
Explanation
The hypothalamus is a part of the brain that is located below the thalamus, it is an area of the brain where several and very important homeostatic regulatory functions of the organism are integrated. Its main function is to link the autonomic nervous system with the endocrine system. Other functions are to control body temperature, control thirst and urine production (water balance in the body), control food intake, control uterine contractions and milk ejection in mammals, the coordination of the nervous system Autonomous, which affects smooth muscle and cardiac activity, influences behavior and expression of emotions. Therefore, the correct answer is B. Hypothalamus
