Which of the following statements regarding DNA fingerprinting is false?a) DNA fingerprinting cannot be used for paternity testingb) DNA profile using STR (short terminal repeats) is unique to an individualc) PCR is used for DNA profilingd) Forensic analysis makes use of SNPs (single nucleotide polymorphisms) in coding sequences to distinguish between individuals
Please answer these two questions regarding PCR:
a) Why do you need to perform PCR on DNA obtained from a crime scene?
b) Why so forensic labs analyze non-coding DNA rather than genes?

The technique used to isolate this DNA is the polymerase chain reaction, which is capable of amplifying very small amounts of DNA a millionfold. Critics have claimed that the DNA isolated from dinosaur bones is not purely of ancient origin, but instead has been contaminated by DNA from present-day organisms such as bacteria, mold, or humans. What precautions, analyses, and control experiments could be carried out to ensure that DNA recovered from fossils is truly of ancient origin?arrow_forward
- You purified the genome of the coliphage X174. After analysis, you find that its composition is 25 percent A, 33 percent T, 24 percent G, and 18 percent C. Based on this finding, which of the following prediction would you make for the coliphage $X174? The genome of coliphage X174 is double-stranded DNA. The genome of coliphage X174 is single-stranded DNA. The genome of coliphage X174 is single-stranded RNA. The genome of coliphage $X174 is double-stranded RNA.

You are characterizing a newly discovered organism . You have noticed that the organism grows on two carbon sources - sucrose and mannitol . Whenever you add both sugars to the medium , sucrose will be completely metabolized before mannitol . a ) What is this growth pattern called ? b ) Describe a possible growth curve of sequential metabolism of the sugars . arrow_forwardIs the DNA you extracted is pure? What are the possible impurities? What can we do with the DNA once we have purified it? Discuss different techniques and technologies associated with this. Imagine that there is an E. coli outbreak in your area, and you would like to test the kangkong from your local grocery store. How could you modify this protocol to extract DNA from the kangkong (to identify the species) and check for presence or absence of E. coli.? Keep in mind that (i) E. coli is free-living and not an endosymbiont, and (ii) plant cells are encased in both a cell membrane and cell wall.arrow_forward
- For what purpose is DNA fingerprinting used A) to sequence DNA from bacteria B) to separate DNA fragments C) to identify individuals who have committed crimes D) to identify single nucleotide polymerasearrow_forward1.) What characteristics of VNTR and STR make them useful for DNA fingerprinting? 2.) How does PCR minimize the problems associated with degraded DNA? 3.) What factors can cause DNA to become degraded? 4.) If Ethidium bromide was not added to a gel, what would happen? 5.) How can you tell if an individual is heterozygous for the D1S80 marker? 6.) If a negative control produces a band, what does this indicate? 7.) In an experiment, a student’s sample amplified for D1S80 produced 3 bands. It was the only DNA sample run on the gel. The student knows that there was no problem with the Thermocycler or primers because the other students in the class had the expected results of only one or two bands. What is the most likely explanation for these results?arrow_forwardPlease answer these two questions regarding PCR a) First question you must use the image: What is the DNA profile for suspect B for the TH01 locus? b) What determines the target sequence amplified in PCR?arrow_forward
