How conclusive is the evidence of DNA fingerprinting?
DNA fingerprinting is considered highly conclusive in identifying individuals due to the uniqueness of each person's DNA profile. The probability of two individuals having identical DNA fingerprints is extremely low, making it a powerful tool in forensic science. However, while it is highly reliable, factors such as sample contamination or improper handling can affect results. Overall, when conducted correctly, DNA fingerprinting provides strong, though not infallible, evidence for identification purposes.
Why footprint is not conclusive evidence?
A footprint alone is not conclusive evidence because it may not definitively identify a specific individual. Footprints can be similar across multiple people or animals, and other factors like size variation, distortion, and contamination can affect the accuracy of footprint evidence. Additional evidence, such as DNA or eyewitness testimony, is typically needed to support the significance of a footprint in an investigation.
Why was it difficult to use DNA as evidence in a crime pcr was invented?
you need many copies of DNA for DNA fingerprinting
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.
What causes DNA evidence to deteriorate?
DNA evidence can deteriorate due to exposure to heat, humidity, light, and contamination with substances like chemicals or microorganisms. Environmental factors such as sunlight, moisture, and high temperatures can break down DNA molecules over time, impacting their integrity and suitability for analysis. Additionally, improper storage and handling of DNA samples can compromise their quality and lead to degradation.
What factors that can affect a person appearance?
Genetic factors(DNA)
How long does DNA last in hair and what factors can affect its preservation?
DNA can last in hair for a long time, potentially thousands of years under the right conditions. Factors that can affect its preservation include exposure to sunlight, moisture, heat, and chemicals.
Why footprint is not conclusive evidence?
A footprint alone is not conclusive evidence because it may not definitively identify a specific individual. Footprints can be similar across multiple people or animals, and other factors like size variation, distortion, and contamination can affect the accuracy of footprint evidence. Additional evidence, such as DNA or eyewitness testimony, is typically needed to support the significance of a footprint in an investigation.
How long can DNA forensic evidence last in clothes?
DNA forensic evidence can potentially last for many years on clothes if they are properly stored and preserved. Factors like exposure to sunlight, moisture, and chemical contaminants can degrade DNA over time, so evidence should be collected and stored in a controlled environment to ensure its longevity. Generally, DNA can be detected on clothes for several years if they are handled and preserved correctly.
What are the arguments for and against DNA evidence?
There are many arguments for and against DNA evidence. One argument is that it cannot be disproved as deciding evidence.
Factors that affect the rate of DNA migration in Agarose gels electrophoresis.?
The main factors affecting the rate of DNA migration in agarose gel electrophoresis include the size of the DNA fragments (smaller fragments migrate faster), the concentration of agarose in the gel (lower concentrations allow DNA to migrate faster), and the strength of the electric field applied (higher voltage leads to faster migration). pH and buffer composition can also affect migration rates.
Are DNA tests done for all murder suspects?
DNA tests are not conducted for all murder suspects, but they are increasingly common in homicide investigations, especially when biological evidence is available at the crime scene. Law enforcement may prioritize DNA testing based on the circumstances of the case, such as the availability of physical evidence and the potential for a suspect to be identified through DNA. Additionally, legal protocols and resources can influence whether DNA testing is pursued in a particular case. Ultimately, the decision to conduct DNA tests depends on various factors, including investigative strategy and the specific evidence at hand.
What three factors affect the organisms trait?
Three factors that affect an organism's traits are genetics (inherited DNA), environmental conditions (such as temperature or availability of resources), and interactions with other organisms (such as competition or symbiosis).
Why was it difficult to use DNA as evidence in a crime pcr was invented?
you need many copies of DNA for DNA fingerprinting
What factors is most likely caused a mutation in DNA?
There are two main factors that cause a mutation in DNA. These factors include: the DNA fails to accurately copy itself and external influence cause a breakdown in the DNA.
Which of the following is not a type of latent evidence?
dna
