DNA sequencing can help us to identify mutations withingenes. The following data are derived from an experimentin which a normal gene and a mutant gene have been sequenced:
Short tandem repeats (STR) profiling is based on O A. the fact that many foods are being genetically modified and this test allows food health officials to identify the transgenic ones. 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.
As genetic testing becomes widespread, medical records will containthe results of such testing. Who should have access to thisinformation? Should employers, potential employers, or insurancecompanies be allowed to have this information? Would youfavor or oppose having the government establish and maintain acentral database containing the results of individuals’ genomescans?
Select the definition of a microsatellite. short pieces of DNA surrounding the periphery of the nucleus short pieces of DNA that flank most genes segments of DNA cut by restriction enzymes small DNA sequences that are repeated consecutively a few times to many times O pieces of DNA that can move through the genome by transposition How are microsatellites used in genetic studies? to identify individuals within a population used as markers in the sequencing of the human genome to identify genetic variants in genome-wide associations studies to test if a population is in Hardy–Weinberg equilibrium to transfer genes between organisms O O
What is DNA fingerprinting? what is its application/s (legally and medically) and limitation/s? How does this technology work? i.e in genomic DNA identification? What is its molecular basis? How does molecular biology paved way for the emergence of this technology?
When gene probes, fi ngerprinting, and sequencing make it possible for you to know about genetic diseases in you or one of your children, would you wish to use this technology to fi nd out?
DNA markers have greatly enhanced the mapping of genes in humans. What are DNA markers, and what advantage do they confer?
Regarding STR markers used in forensic science. Tick all the correct statements: no correct statement the PCR primers used to amplify STRs are located in the repeat units PCR primers to amplify STRs are located on both sides of the repeat units the PCR primers used to amplify STRs are coupled to a fluorochrome which is essential for the detection of amplicons they are absent from the gonosomes the allelic frequencies of STR markers vary according to the ethnicity of the individuals genotyped they are present homogeneously throughout the nuclear genome
Is whole-genome sequencing for an individual beneficial? Why or why not?
STR markers: are point mutations detectable by DNA sequencing are variations in the number of repeats of very short DNA motifs (2-10 nucleotides) □have high polymorphism are mutations leading to proteins or blood groups that can be differentiated by antigenic testing from a blood sample ☐have low polymorphism no correct answer are changes of a few nucleotides leading to the absence or presence of a site recognized by a restriction enzyme are variations in the number of repeats of medium-sized DNA motifs (10-100 nucleotides) can be located in coding sequences are located exclusively on autosomes
Which ingredient will allow the DNA to form cloudy clumps which can be collected with tweezers salt rubbing alcohols detergent solution water What is the purpose of PCR? To copy and then make many copies of a specific region of DNA To copy the entire human genome To make just a few copies of DNA To reveal the sequence of a piece of DNA If enzyme catalase has an optimum pH of 7.0, What do you think will happen en the pH is lowered to 3.0? The rate of its enzyme action is increased. Its enzyme action is not affected at all. The rate of its enzyme action is decreased. Its enzyme action ceases or stops.
