Please read the paragraph regarding transcription termination and fill in the blanks with words from the word bank below (not all of the words will be used): There are two known mechanisms of transcription termination in prokaryotes. One mechanism requires a protein complex called . This protein complex binds to the , which is located on the RNA that is being transcribed. This protein complex then moves toward the stalled RNA polymerase complex and unwinds the RNA from the DNA. A second mechanism for termination in prokaryotes requires an RNA termination sequence that contains a secondary structure called a followed by a string of nucleotides. Transcription termination for RNA Polymerase II in eukaryotes happens when the termination consensus sequence, , is transcribed leading to cleavage of the mRNA 11-30 nucleotides downstream of the termination sequence. Once cleavage occurs, binds to the 5′ end of the mRNA that is still attached to the RNA polymerase/DNA complex and degrades the remaining mRNA. This leads to the dissociation of the RNA polymerase from the DNA.

The size of the domestic dog genome is 2.4 billion (2.4 x 109) base pairs in length. Approximately how many nucleosomes would you expect to be in an average dog genome? Approximately how many copies of histone H2A protein you would find per dog genome? *for both quesitons assume the core DNA + linker DNA=200 bp

Drosophila have large chromosomes in their salivary glands called polytene chromosomes. When these chromosomes are exposed to the hormone, ecdysone (the molting hormone), regions of the chromosome form chromosomal puffs. What affect does chromosomal puffing have on transcriptional activity of genes in this region (i.e. is there more or less transcription in these regions)? In class we talked about a few experiments testing hypotheses regarding the relationship between the state of chromosome and the amount of transcription taking place. What conclusions were drawn from these experiments?
