Answer #1

Enhancers are DNA regulatory sequences controlling temporal and tissue specific gene expression. It is a short region of dna that can be bound by activators to increase the transcription of a paricular gene. Enhancers act through a variety of transcription factors that ensure their correct match with target promoters and consequent gene activation.

In short, an enhancer functions to enhance the transcription. For that, it does not need to be near the gene of interest.

alterations in enhancers lead to misregulation of gene exprression

The translocation rate of RNA polymerase II is 30 nucleotides per second for a gene you study that is 50,000 nucleotides in length. This gene contains 3 exons and 2 introns. The translocation rate of the ribosome on the resulting mRNA is also 30 nucleotides per second. Assuming that the translocation rates of RNA polymerase II and the ribosome are the rate limiting steps in their respective processes, which process (transcription or translation) do you expect to produce more product...
