- Part 4. Putting It Together 1) Consider the diagram below as well as the given information. This diagram represents a piece of circular DNA which was cut in 4 separate reactions (4 different test tubes, each with some of this DNA in it). One digest was done with AvaI, another with ClaI, a third with EcoRV, and a fourth with ScaI. The locations of the recognition sequences for each restriction enzyme are shown along with the location of that site in bp along the circle (it goes clockwise from position 1). You run an agarose gel with a molecular weight marker in the first lane, the AvaI digest in lane 2, the ClaI digest in lane 3, the EcoRV digest in lane 4, and the ScaI digest in lane 5. a) Use the space below and draw out the agarose gel described above. Use your drawing to answer the next questions. b) How many bands of DNA are there in lane 3? c) How many bands of DNA are there in lane 5? d) There would be 2 bands of DNA in lane 4. How big are they? e) Which lane…4a in context to taking genomic DNA from eukaryotic cells and randomly shearing it into pieces of a constant size, why do some of the genomic DNA fragments re-nature so much more quickly than other fragmentsWhich statements are true? Explain why or why not.1 Because the DNA double helix is only 2 nm wide—well below the limit of resolution of the light microscope—it is impossible to see chromosomes in living cells withoutspecial stains.2 A fluorescent molecule, having absorbed a singlephoton of light at one wavelength, always emits it at a longer wavelength.

- expalin Yeast centromeric DNA sequences21. The difference between a nucleoside and nucleotide is: Group of answer choices 1. A nucleoside consists of the sugar with a nitrogenous base, whereas a nucleotide has a sugar with a nitrogenous base and phosphate groups attached to the sugar. 2. Nucleotides contain deoxyribose sugar and nucleosides contain ribose sugar 3. Nucleotides are involved in eukaryotic DNA replication, while nucleosides are used in bacterial DNA replication 4. A nucleotide consists of the sugar with a nitrogenous base, whereas a nucleoside has a sugar with a nitrogenous base and phosphate groups attached to the sugar.MULTIPLE CHOICE Read the questions below carefully. There is only one correct answer for each question. 1. In a DNA sample of Escherichia coli (a bacteria), 23.6% of the nitrogenous bases are thymine. What percentage of cytosine nitrogen bases is present in this sample? a) 76.4% b) 23.6% c)26.4% d) 52.8% 2. If the adenine is located on the Z strand as shown (see attachement 3) , then on the W strand, in the same place, we should find: a) Uracil b) Adenine c) Thymine d)Cytosine 3. Which of these deletions best represents a chromosomal deletion? (see options in attachment 3) 4. It is known that RNA is a nucleic acid responsible for the synthesis of proteins. However, there is another nucleic acid alongside RNA: DNA. What role does the latter play in relation to RNA? a) RNA is synthesized in the cell in case too large a mutation damages the DNA. b) DNA has the reproductive genetic code of all cells and passes it on to RNA. c) DNA directs the synthesis of enzymes, while RNA synthesizes…
- Nutritional requirements of white verses red yeast What is the differences in the ability of different strains to grow on different mediums. Propose a hypothesis that helps to explain the presence of red yeast colonies. Why it is more common for cells to be killed by UV light than to become red. Hint: think about how mutagenesis occurs.1b) Prokaryotic DNA is normally slightly negatively supercoiled, which can lead to "DNA breathing". How or why does supercoiling lead to DNA "breathing"?The sequence of the DNA template strand is 3’– GACTTCC – 5’ What is the sequence of the DNA informational strand?
