- 1a) Why is it possible for you to study the eye colour gene by extracting cheek cells? a. Because the nucleus of every cell in the human body contains the same genetic information. b. Because the cheek cells are located near the cells of the eye and so they are able to exchange DNA. c. Because all genes in the human body are expressed at all times so it is easy to study them. d. All of the above are possible explanations. 1b) What is the purpose of heating the sample to 75°C following addition of the 0.2M NaOH solution? a. To denature the histone proteins that are keeping the DNA tightly coiled. b. To ensure that all the DNA is removed from the swab in preparation for PCR. c. To breakdown the cheek cell membrane to release the DNA from the cell. d. It breaks down the circular DNA down into linear fragments so that they will be easier to visualize.iarrow_forwardWith the many high throughput experiments that are used in biomedical research, how are some ways to integrate those datasets using systems biology?

What unites them and sets them apart?arrow_forwardThe goal of most gene therapies is to insert a healthy copy of a gene into the genome. Besides CRISPR, techniques for integrating DNA into the genome do not target that DNA to a particular genomic location and thus different cells end up with the DNA sequence in different positions. A. It has been shown that where the healthy gene integrates is heavily influenced by chromatin. Why? B. The same gene integrated into different locations in the genome will be expressed differently. Why? C. Over time the expression of an integrated gene will change, usually decreasing. Describe how you think the cell downregulates expression of an integrated gene.arrow_forward
