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
Why does the probe bind to a specific site on a chromosome?
Place the steps of the double-strand break model of recombination in order.
DNA polymerase fills in gaps in the DNA
exonuclease generates 3' single-stranded overhangs
DNA ligase seals the nicked DNA
First step
Last step
Answer Bank
homologous region of intact homolog is invaded by free end
endonuclease cleaves both strands of one homolog

- 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.arrow_forwardSelect the CORRECT pairing.
