Questions 1-5. Please fill in the blank below with the corresponding structures indicated below in the diagram: Please ignore the fact that the fragments are colored blue and green. The coloration has no significance to this question. Also, please don’t forget to answer question 6! 1. Lagging strand= 2. A single Okazaki fragment= 3. 5′ end of fragment labeled “D”= 4. Replication fork= 5. How many primers are required to replicate all of the DNA fragments in the above diagram (include both lagging and leading strand)?=

A researcher named Erwin Chargoff determined the relative proportion of the different nucleotides in different species and came up with what we know today as Chargoff’s rule. What is the percentage of Cytosine, if the percentage of Guanine is 24%? What would be the percentage of Adenine in the same species?

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?
