What role do insulator sequences play in the regulation of eukaryotic transcription? See Section 13.1 (Page 479) . What role do

insulator sequences play in the regulation of eukaryotic transcription? See Section 13.1 (Page 479) . They block binding of transcription factors to cis-acting promoter elements. They block binding of transcription repressors to cis-acting promoter elements. They block binding of transcription factors to enhancers. They block communication between enhancers and nontargeted promoters.

Answer:

D. They block communication between enhancers and non-targeted promoters

Explanation:

Insulator sequences are the group of DNA sequences that protect the protein-coding regions of the DNA from the surrounding regulatory sequences. Some insulator sequences are present between the enhancers and promoters of a gene. These insulator sequences do now allow these enhancers to regulate the expression of genes by sending inappropriate signals.

However, if the insulator sequences are not present between the enhancers and promoters of certain genes but are located somewhere else, enhancers can upregulate the expression of these genes.

Answer:

The P waves undergoes compression and dilation during motion in its direction of propagation. This waves reaches the station first because the P waves travels at a speed, that is much faster in comparison to the S waves. The S waves are the secondary waves and are commonly known as the shear waves.

The P waves have the ability to travel in both solid as well as in liquid, whereas the S waves can propagate only in solid region because they are absorbed at the core-mantle boundary.

Thus, the P waves will arrive the station first and the difference between the arrival of P and S waves are plotted in the graph that helps in depicting the epicenter and the amount of energy released during an earthquake.

What is the correct order of the stages of speciation?
guapka [62]

First Stage: Separation

Speciation usually begins when a part of a population becomes separated from the rest of their species.

Second Stage: Adaptation

Adaptation in speciation is quite similar, though the groups may evolve different sets of traits if the environmental conditions differ for each group.

Third Stage: Reproductive Isolation

Reproductive isolation is when groups of a same species are reunited and cannot interbreed with each other anymore, so they are now identified as different species.
