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.
Are there any downsides to DNA evidence?
There are a few downsides to DNA evidence: It has been suggested that the prominence of DNA evidence on TV shows has caused juries to expect irrefutable DNA evidence before convicting someone. This may be a problem if other forms of evidence are ignored. DNA evidence can only be obtained in instances where biological substances are left behind or exchanged. This only occurs in a minority of cases. DNA evidence sometimes only proves that the person was present at the scene - it does not always prove guilt. However, if a person's DNA is found at the scene, this may be perceived as proof that they committed the crime.
What factors affect DNA evidence?
Several factors can affect the reliability of DNA evidence, including sample quality, contamination, degradation, mixtures of DNA from multiple individuals, and potential human error during collection and analysis. It is crucial for forensic scientists to carefully consider these factors when interpreting DNA evidence in criminal investigations.
Why is DNA evidence difficult to refute in court?
DNA evidence is difficult to refute in court because it is highly accurate and reliable. The technology used to analyze DNA is advanced and has a low margin of error, making it a strong piece of evidence. Additionally, DNA profiles are unique to each individual, making it highly improbable for someone else to have the exact same DNA profile.
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.
Which of these is the best description of Alzheimer's disease?
a progressive disease that causes the brain to deteriorate in a continuous process
What causes hip replacements to deteriorate?
Normally, the hip replacement will 'deteriorate' due to wear, as the particles can lead to a body reaction leading to osteolytic loosening. Though some patients don't get this.
Why do planets with atmospheres have less impacts?
The atmosphere causes the object that is impacting or hitting the earth and causes it to burn and deteriorate as it lands on the earth's Surface.

What evidence can be used for DNA fingerprinting at a crime scene?
DNA evidence from blood, hair, saliva, or other bodily fluids found at the crime scene can be used for DNA fingerprinting. This evidence is compared to the DNA profiles of suspects to determine if a match exists, helping to identify or exclude individuals involved in the crime.

Yes, DNA fingerprinting is a powerful tool for solving crimes because it can definitively link a suspect to a crime scene or victim.

However, it is important to consider the chain of custody and proper handling of DNA samples to ensure the integrity of the evidence.
