New legislation is typically proposed by the Commission, and then approved by the European Union's Council and Parliament. The Commission then guarantees that the laws are correctly applied as the member nations put them into effect.
The European Council often does not pass laws. It can, however, come to an agreement on modifications to the EU Treaty on its functioning. Its principal responsibility is to choose the political course for the EU.
The majority of the time, the EU Council, European Commission, and European Parliament create the rules and policies that are enforced across the board. They adhere to a procedure known as Ordinary Legislative Procedure.

The body of a woman is found buried in a field. Although much of the body has decomposed, her clothes are mostly intact. She appears to have died of suffocation but has no other visible injuries. However, there are bloodstains on both her shirt and pants. Based on location and description, police suspect this is the body of a woman who went missing about 15 years ago. What rationale might a forensic scientist have in choosing whether it’s worth it to analyze the bloodstains to see if they match a suspect?
A.
The blood would no longer produce DNA.
B.
Dried blood can still produce nuclear DNA after 20 years.
C.
There’s probably not enough blood to get a good sample.
D.
The bloodstains probably belong to the victim.
The rationale a forensic scientist might consider in determining whether it is worthwhile to analyze the bloodstains to see if they match a suspect could be option B. Dried blood can still produce nuclear DNA after 20 years.
Is dry blood usable for DNA ?Forensic scientists understand that under certain conditions, dried blood can retain viable DNA for extended periods, even up to several decades. Through proper preservation techniques and specialized laboratory procedures, it is possible to extract and analyze the nuclear DNA present in dried bloodstains.
By comparing the DNA profile obtained from the bloodstains with the DNA of potential suspects, forensic scientists can establish a potential match or exclusion, providing valuable evidence in the investigation.

Officers responded to a robbery in progress at a convenience store. A young man with red hair was seen fleeing the scene. Investigators found blood on a broken plate of glass at the storefront and analyze it for DNA. Forensic biologists are unable to match the DNA to anyone in the crime database, so they turn to SNP analysis to do what?
A.
Check the blood for mutations
B.
Double check the information.
C.
See if the DNA predicts the blood is from a redhead.
D.
Evaluate if they did the first test correctly.
When forensic biologists are unable to match DNA from a crime scene to any individual in the crime database, they may use SNP (Single Nucleotide Polymorphism) analysis to further explore the DNA sample.Option C is the correct answer.
SNP analysis looks for differences in single nucleotides within a DNA sequence. In the case of the convenience store robbery, detectives would use SNP analysis to discover if the DNA sample included certain genetic markers associated with red hair.
Red hair is a genetic characteristic induced mostly by a mutation in the MC1R gene. This gene is in charge of producing melanin, the pigment that controls hair color. Forensic biologists can determine if an individual will have red hair by analysing the SNP patterns associated with the MC1R gene.
As a result, forensic biologists can establish whether the DNA sample obtained on the broken plate of glass includes the genetic markers associated with red hair by doing SNP analysis on it. If the SNP analysis indicates that the DNA came from a person with red hair, it could give a vital lead for police, reducing their hunt for the perpetrator.
Therefore the correct answer is option C
