Summary Introduction
To describe: The steps to find out the presence of a gene in humans that can cause the retinal degeneration by using the procedure of Southern blotting.
Introduction: A method for transferring DNA fragments from a gel to a membrane filter and screened with probes to identify a fragment of interest is called “southern blotting.”
The fragment of interest can be used in hybridization experiments.

The technique of fluorescence in situ hybridization (FISH) is described. This is another method for examining sequence complexity within a genome. In this method, a DNA sequence, such as a particular gene sequence, can be detected within an intact chromosome by using a DNA probe that is complementary to the sequence.For example, let’s consider the β-globin gene, which isfound on human chromosome 11. A probe complementary to theβ-globin gene binds to that gene and shows up as a brightly colored spot on human chromosome 11. In this way, researchers can detectwhere the β-globin gene is located within a set of chromosomes. Becausethe β-globin gene is unique and because human cells are diploid(i.e., have two copies of each chromosome), a FISH experimentshows two bright spots per cell; the probe binds to each copy ofchromosome 11. What would you expect to see if you used thefollowing types of probes?A. A probe complementary to the Alu sequenceB. A probe complementary to a tandem array near…

- A number of advances have been made in biotechnology. CRISPR/Cas9 one of the most controversial, and has had a lot of media attention in recent years. It is a method by which scientists can precisely edit DNA sequences at exact locations. Benefits obviously include the potential to “repair” mutated genes that cause disease. In fact, preliminary results from one of the earliest clinical trials of CRISPR/Cas9 provide evidence that the technique is safe and feasible to use for treating human diseases. What other potential applications of this application do you see (you can use any organisms to illustrate your answer)? What are the potential dangers or downsides of using this technology? Do you think this technology should be used in gene editing in humans? Explain your stance.arrow_forwardThe temperature at which the primers and target DNA hybridize may be changed to influence the stringency of PCR amplification. What effect will changing the hybridization temperature have on the amplification? Let's say you have a certain yeast gene A and want to check whether it has a human equivalent. How might managing the hybridization's rigor benefit you?arrow_forwardExperiment A microarray was hybridized with a mixture of two differentially labeled fluorescent cDNAs, one prepared using retinal RNA of 1-day-old mice (labeled with a green fluorescent dye) and the other prepared using retinal RNA of 28-day-old mice (red fluorescence). The two probes were prepared from identical amounts of retinal tissues and were mixed together for hybridization to the microarray. Unhybridized probes were washed away, and the microarray was photographed in a fluorescence microscope.arrow_forward
- Analyzing Cloned Sequences A base change (A to T) is the mutational event that created the mutant sickle cell anemia allele of beta globin. This mutation destroys an MstII restriction site normally present in the beta globin gene. This difference between the normal allele and the mutant allele can be detected with Southern blotting. Using a labeled beta globin gene as a probe, what differences would you expect to see for a Southern blot of the normal beta globin gene and the mutant sickle cell gene?arrow_forwardWhich of the following best describes the process of DNA sequencing? a. DNA is separated on a gel, and the different bands are labeled with fluorescent nucleotides and scanned with a laser. b. A laser is used to fluorescently label the nucleotides present within the DNA, the DNA is run on a gel, and then the DNA is broken into fragments. c. Nucleotides are scanned with a laser and incorporated into the DNA that has been separated on a gel, and then the DNA is amplified with PCR. d. Fragments of DNA are produced in a reaction that labels them with any of four different fluorescent dyes, and the fragments then are run on a gel and scanned with a laser. e. DNA is broken down into its constituent nucleotides, and the nucleotides are then run on a gel and purified with a laser.arrow_forwardYou learned in the chapter that an STR locus is a locus where alleles differ in the number of copies of a short, tandemly repeated DNA sequence. PCR is used to determine the number of alleles present, as shown by the size of the DNA fragment amplified. In the Figure below are the results of PCR analysis for STR alleles at a locus where the repeat unit length is 9 bp, and alleles are known that have 5 to 11 copies of the repeat. Given the STR alleles present in the adults, state whether each of the four juveniles could or could not be an off-spring of those two adults. Explain your answers.arrow_forward
- Cloning Genes Is a Multistep Process In cloning human DNA, why is it necessary to insert the DNA into a vector such as a bacterial plasmid?arrow_forwardFigure 17.7 You are working in a molecular biology lab and, unbeknownst to you, your lab partner left the foreign genomic DNA that you are planning to clone on the lab bench overnight instead of storing it in the freezer. As a result, it was degraded by nucleases, but still used in the experiment. The plasmid, on the other hand, is fine. What results would you expect from your molecular cloning experiment? There will be no colonies on the bacterial plate. There will be blue colonies only. There will be blue and white colonies. The will be white colonies only.arrow_forwardCloning Genes Is a Multistep Process The following DNA sequence contains a six-base sequence that is a recognition and cutting site for a restriction enzyme. What is this sequence? Which enzyme will cut this sequence? (See Figure 13.5 for help.) 5 CCGAGGAAGCTTAC 3 3 GGCTCCTTCGAATG 5arrow_forward

O B. the fact that you can clone mammals through fusion of one somatic (non-sex) cell with an egg cell whose nucleus has been removed O C. the fact that one strand of DNA can be turned into millions of identical copies by a process that heats and cools DNA and builds it using DNA polymerase and primers. OD. the fact that people's DNA is filled with short sequences, like "TCAT" that are found in different numbers in each person.arrow_forward
