Suppose two suspects in a crime have DNA profiles that match the one DNA fragment tested. What should happen next?
A)Both suspects must be guilty and should be charged with the crime.
B)The test should be repeated because a mistake must have occurred.
C)A different hair or blood sample taken from the crime scene should be analyzed for the same DNA fragment.
D)The sample taken from the crime scene should be analyzed for multiple DNA fragments.
4. Suppose that the DNA pattern generated from the hair sample at the crime scene did not match any of the DNA patterns of the suspects. Which conclusion can be drawn?
A)Only one of the suspects can be ruled out.
B)None of the suspects can be ruled out.
C)All of the suspects can be ruled out.
D)A mistake must have been made and the test will have to be run again.
please help. thanks. :)
DNA Sequencing and Analysis Quick Check Answers: C, A, D, C. 100% Correct. Have fun Connections Academy Students.
THE ANSWERS ARE CADC NOT CABC
The first one is D, because the probability of multiple suspects to share one fragment that is tested is much higher than when multiple fragments are tested. The FBI uses 13 when running crime scene tests.
The second one is C, if multiple patterns are used in testing and neither suspect share ANY of them then it is generally safe to exclude them from the investigation.
the right answers are the answers the fake Ms. Sue gave
somebody please help me. I have no clue what the answers are. please please please PLEASE help me!!!
thank you so much!
C, A, D, C 100%
Don't listen to Ms. Sue like the person above said. She wants us to fail lol.
Hope I helped :)
My heart goes out to your grandpappy. Nice rocket ship:)
For the first question, when two suspects have DNA profiles that match the one DNA fragment tested, it does not necessarily mean that both suspects must be guilty. To determine the next step, we need to consider the available options.
A) Both suspects must be guilty and should be charged with the crime: This conclusion cannot be drawn solely based on a match in one DNA fragment. It is possible that there is another explanation for the match, such as a coincidence or a common genetic trait.
B) The test should be repeated because a mistake must have occurred: This option is a valid consideration. Whenever there is a match in DNA profiles, it is important to double-check the accuracy of the test to rule out any potential mistakes.
C) A different hair or blood sample taken from the crime scene should be analyzed for the same DNA fragment: This option should also be considered. Testing other samples from the crime scene can help confirm the consistency of the DNA evidence and strengthen the case against the suspects.
D) The sample taken from the crime scene should be analyzed for multiple DNA fragments: This option is usually the next logical step. Analyzing multiple DNA fragments can increase the accuracy of the identification process and provide more conclusive evidence.
In conclusion, for the first question, options B, C, and D should be considered, while option A should be taken with caution. The specific course of action depends on the context of the investigation and the available samples.
Now, for the second question:
When the DNA pattern generated from the hair sample at the crime scene does not match any of the DNA patterns of the suspects, we need to evaluate the available options.
A) Only one of the suspects can be ruled out: This option assumes that there is a possibility that one suspect may still be guilty, which might be the case if the DNA evidence is not the only determining factor.
B) None of the suspects can be ruled out: This option suggests that the DNA evidence is inconclusive in identifying any of the suspects. It implies that the investigation needs to be continued by examining other evidence or exploring alternative leads.
C) All of the suspects can be ruled out: This option suggests that none of the suspects are connected to the crime based on the available DNA evidence.
D) A mistake must have been made, and the test will have to be run again: This option should also be considered. It is possible that an error occurred during the testing process, leading to an unreliable outcome.
In conclusion, for the second question, options A, B, and D can be valid considerations depending on the context of the investigation and the strength of other evidence. Option C may be less likely since it assumes that the DNA evidence is the only determining factor in the investigation.
I mean't C, A, B, C
oops :/
