Answer:
An Enhancer
Explanation:
Enhancers are the regulatory sequences and are generally located 80-160 base pairs upstream of the transcription start site. Enhancers have bidirectional elements that are involved in the initiation of transcription. Enhancers serve as the binding sites for activators to increase the concentration of activators in the vicinity of the promoter and thereby increase the rate of transcription of the gene.
According to the given information, the loss of a regulatory sequence led to a reduced level of transcription of the gene. This means that the regulatory sequence was involved in the upregulation of transcription. The presence of the sequence far away from the promoter makes it an enhancer.
The first step is to identify the problem. There are factors to consider in keeping a plant or a tree healthy. These include water, oxygen, sunlight, soil, nutrients, climate, and other environmental conditions. If the environment seems to suit the other trees in the garden, ruling out other factors can be useful in determining why only one tree seems to be unhealthy. Once the problem is identified, a scientific investigation must be done to gather data and pieces of evidence which can explain why this event actually occurred. One of the best ways to gather evidence is through observing the tree and checking other signs which might identify if the tree is diseased. Once the gathered data are analyzed and the cause is identified, proceed in thinking of ways on how to solve it. In seeking a solution, it is best to ask information from experts and proper authorities.
Answer: The natural world should be disturbed as little as possible in an experiment.
Explanation: I just took the quiz
\The common use of epochs during the Cenozoic helps paleontologists better organize and group the many significant events that occurred during this comparatively short interval of time. Knowledge of this era is more detailed than any other era because of the relatively young, well-preserved rocks associated with it.
