1. In a couple of sentences, explain how eukaryotic activator proteins (that are usually gene-specific transcription factors) can enhance transcription even when bound to sequences hundreds or thousands of nucleotide pairs away from a gene’s promoter. 2. Describe three common characteristics of transcription factors. The characteristics may relate to structure, or mechanism of action (PLEASE ANSWER BOTH PLEASE)

1. a)how is it possible for such drugs to selectively kill bacterial cells and not our own cells? b)Provide an example of post-translational regulation of protein activity and explain the advantage of regulating each protein/process at the post-translational level instead of the transcriptional level.
New drugs are being developed that decrease DNA methylation and prevent the removal of acetyl groups from histone proteins. Explain how these drugs could affect gene expression to help kill tumor cells.
Discuss how degeneracy of the genetic code makes cells more robust to mutations.
Discuss Concepts The normal form of a gene contains the nucleotide sequence: When this gene is transcribed, the result is the following mRNA molecule: In a mutated form of the gene, two extra base pairs (underlined) are inserted: What effect will this particular mutation have on the structure of the protein encoded in the gene?
