Question
Chapter 9.3, Problem 1CC
Summary Introduction
To identify:
The reason why the nuclei resulting from experiment 2 contain different amount of DNA, as refer to Figure: 9.14 “Inquiry”, in the textbook.
Introduction:
With reference to the data in Figure: 9.14 “Inquiry”, in the textbook, the researchers investigated that “a cell’s progression by the cell cycle is controlled by cytoplasmic molecules”.
As given in experiment 2, researchers cause the fusion of M phase with a cell of G1 phase. The G1 phase began to start mitosis. This process resulted in the formation of a spindle and condensation of the chromosomes even though the chromosome had not been duplicated.

Solution 1 contains single stranded viral DNA while Solution 2 has double stranded form of the same viral DNA. Both solutions contain 1 mg/ml of DNA. You then expose each of these solutions to UV light at 260 nm. Which of the following results would you expect to see after UV light exposure? a.Neither solution will absorb any UV light but the DNA in both solutions will be broken by the action of the UV light. b.Solution 1 will absorb less light than Solution 2 c.Solution 1 will absorb more light than solution 2. d.Nothing will occur. DNA can only absorb UV light if it is interchelated with ethidium bromide. e.Both solutions will absorb the same amount of light since their concentrations are the same.arrow_forwardThe Bacteria Escherichia coli DNA genome has a molecular mass of about 3.1 X 10 9 D.

You treat the samples in exactly the same way (adding same amount of enzyme, buffer and time) to partially digest the chromatin with micrococcal nuclease, separate the DNA from the protein, and run the DNA on an agarose gel. You see the pattern below: Lane 1 2 3 Approximate size of bands (in base pairs) 200, 400, 600, 800 180, 360, 540, 720 190, 380, 570, 760 Knowing that core-DNA in all cell types is the same what is your explanation for the difference in DNA size in the patterns you observe?arrow_forwardQuestion 2 The discovery of the DNA structure started the modern era of biotechnology.

If so , how ?arrow_forwardQUESTION 9 Imagine that a researcher has a cell from a genetically engineered organism and a clone of that same organism. The researcher uses PCR and then runs a DNA fingerprint on the two samples. What should the researcher find on the gel? O A. The gel will be blank because the heat from the PCR will destroy the DNA. OR The gel will be blank because the heat from the PCR will change the charge of the DNA and cause it to run in the opposite direction, off of the gel and into the buffer. OC. The DNA banding pattern for the two organisms will be identical. O D. The DNA banding pattern for the two organisms will be different because every organism has original DNA.arrow_forwardQuestion 10.
