- DNA Profiles as Tools for Identification A PCR-based paternity test is conducted using STRs that consistently produce a unique DNA fragment pattern from a single chromosome. Examining the results of the following Southern blot, which male(s) can be excluded as the father of the child? Which male(s) could be the father of the child?Which of these is not a tool for comparing DNA sequences? BLAST Fasta PLINK A dotplot e.g. dotletDuring electrophoresis, DNA molecules can easily be separatedaccording to size because all DNA molecules have the samecharge–mass ratio and the same shape (long rod). Would youexpect RNA molecules to behave in the same manner as DNAduring electrophoresis? Why or why not?
- why is recombinant DNA is possible becuase we know dna molecules from all organisms share the same chemical structure and differ only in the nucleotide seqeunce within the identical structureSimilarities between DNA agarose gels and SDS-PAGE are: Both methods use agarose gels. Both methods use electrical charge differences to separate molecules by size. Both methods determine the size of DNA fragments. All the given answers.Which of the following best describes the process of DNA seqencing. a. DNA is seperated on a gel and the different bands are labled with flouroscent nucleotides and scanned with a laser. b. A laser is used to flurorescently label the nucleotides present with in the DNA , the DNA is run on a gel and then the DNA is droken into fragments c. Nucleotides are scanned with a laser and incrprorated into the DNA that has been seperated on a gel and then DNA is amplified with PCR. d. fragments of DNA are produced in a reaction that lables them with any of four different fluroscent dyes and the fragmented then are run on a gel and scanned with laser e. DNA is broken down into its constituents nucleotides and the nucleotides are then run on a gel and purified with a laser
