What are some possible problems or sources of error related to DNA fingerprinting?
Possible problems or sources of error in DNA fingerprinting include contamination of samples, degradation of DNA samples, mislabeling of samples, and human error during the analysis process. These issues can lead to inaccurate results and misidentification of individuals.
What is used to copy dna for dna fingerprinting?
Nuclear transfer
Analysis of fragments of DNA as a form of identification?
Analyzing fragments of DNA involves breaking down the DNA sequence into smaller pieces and comparing them with known DNA samples. This process can be used for identification purposes, such as in forensic investigations or paternity testing, by examining unique genetic markers. The specific pattern of DNA fragments can help distinguish individuals based on their genetic differences.
Which two methods are most often used in DNA fingerprinting?
The two most often used methods in DNA fingerprinting are polymerase chain reaction (PCR) and gel electrophoresis. PCR is used to amplify the DNA samples, while gel electrophoresis is used to separate the DNA fragments based on their size.
Why did the invention of PCR make DNA fingerprinting?
PCR made it possible to produce enough copies for reliable tests.
DNA samples for human DNA fingerprinting can be obtained from?
DNA samples for human DNA fingerprinting can be obtained from a variety of sources, including blood, saliva, hair follicles, and skin cells. These samples contain DNA that can be used for analysis and comparison to create a unique genetic profile for each individual.

Where can you obtain DNA for DNA fingerprinting?
sperm blood hair with attached tissue
What is used to copy dna for dna fingerprinting?
Nuclear transfer
Where is there possibly errors in DNA fingerprinting?
Human error.
Where is there possibility for error in DNA fingerprinting?
Human error.
Can DNA fingerprint be traced in burned body?
Yes, DNA fingerprinting can still be traced in burned bodies, as the DNA sequencing can be extracted from even degraded samples. However, the extent of damage to the DNA and the ability to obtain usable samples can vary depending on the severity of the burning. Specialized techniques may be needed to extract and analyze the DNA from burned tissues.
How do the CSI and NCIS use blood samples?
To obtain DNA profiles.
Do you think DNA fingerprinting is good evidence for solving crimes. why or why not?
Yes, DNA fingerprinting is a powerful tool for solving crimes because it can definitively link a suspect to a crime scene or victim. DNA evidence is scientifically reliable and has high accuracy, which can help prosecutors secure convictions or help exonerate innocent suspects. However, it is important to consider the chain of custody and proper handling of DNA samples to ensure the integrity of the evidence.
