You 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.
Which 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.
Cloning Genes Is a Multistep Process Which enzyme is responsible for covalently linking DNA strands together? a. DNA polymerase b. DNA ligase c. EcoRl d. restriction enzymes e. RNA polymerase
Cloning 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 5
A more modern molecular technique to RFLP fingerprinting is called Amplified Fragment Length Polymorphisms (AFLPs). In AFLP analysis, restriction enzymes are again used to digest genomic DNA into multiple fragments. Next, adapters complementary to restriction site overhangs are ligated to the fragments using an enzyme called DNA ligase. These adapters are complementary to primers used to amplify the fragments using the polymerase chain reaction (PCR). Can you think of any potential benefits of AFLP analysis over RFLP? Explain your reasoning.
Why is Taq polymerase used in PCR rather than other DNA polymerases?a. Taq polymerase is a synthetic enzyme that produces DNA strands ata faster rate than natural polymerases.b. Taq polymerase is a heat-stable form of DNA polymerase that canfunction after exposure to the high temperatures necessary for PCR.c. Taq polymerase is easier to isolate than other DNA polymerases.d. Taq polymerase is the DNA polymerase commonly produced bymost eukaryotic cells.e. All of the above are correct.
Which of the following is true about restriction endonucleases?a) Type I and II requires ATP to move along DNAb) Type I, II and III requires ATP to move along DNAc) Type II requires no ATP and cleaves DNA within recognition sequenced) Type II requires ATP and cleaves DNA within recognition sequence
An important feature of restriction enzymes is that each enzyme only recognizes a specific palindrome and cuts the DNA only at that specific sequence of bases. A palindromic sequence can be repeated a number of times on a strand of DNA, and the specific restriction enzyme will cut all those palindromes, no matter what species the DNA comes from. A linear DNA molecule is represented below. The DNA is represented by one line, although in actuality, DNA has two strands. If the DNA molecule has two restriction sites, specifically two repeats of a specific palindrome sequence, A and B, for a specific restriction enzyme: How many fragments would be produced if the DNA is cut by that enzyme? Number each fragment Which fragment would be the largest? Which fragment would be the smallest?
Why is it important to sequence positive clones derived from PCR cloning? Group of answer choices Errors could have been incorporated during restriction enzyme digestion and so it is important to verify that only the expected protein is produced. Errors could have been incorporated during plasmid DNA extraction and so it is important to verify that only the expected protein is produced. Errors could have been incorporated during PCR and so it is important to verify that only the expected protein is produced. Errors could have been incorporated during cloning and so it is important to verify that only the expected protein is produced.

DNA fingerprinting uses a process called gel electrophoresis to separate the fragments of DNA. Once the DNA fragments are sorted, the pattern of bands can be analyzed. Gel Electrophoresis Procedure The smaller DNA fragments start to move away from the wells and the larger DNA fragments remain closer to the wells. An electric current is passed through the gel. DNA fragments are treated with a dye. A restriction endonuclease is added to the DNA. Using micropipettes, the DNA samples are added to the wells. DNA fingerprint is produced. DNA fragments are produced. The order in which a DNA fingerprint is produced using gel electrophoresis is Answer, Answer, Answer, Answer, Answer, Answer, and Answer.
What is the principle of the SNP (single nucleotide polymorphisms) in the diagnosis of human diseases? a. PCR product of a gene is different from the expected one b. The size of a recombinant DNA is different from the expected one c. Mutation of a single base in a gene makes the size of a band digested by specific restriction enzymes different from the expected one d. The DNA band detected by Southern blot is different from that by Northern blot
