How can scientists use DNA in crime scene investigations? (1 point) They analyze the size of the DNA to determine where a crime
was committed. They analyze the GC content of the DNA to determine how a crime was committed. They analyze the sequence of bases in the DNA to determine who committed a crime. They analyze the age of the DNA to determine when a crime was committed.
Correct answer: C). They analyze the sequence of bases in the DNA to determine who committed a crime
The DNA profiling is used to identify the perpetrator. Forensics scientist is using the nucleotide sequence to find how who has done the crime. They study and analyze the DNA sequence in order to solve the crime.
DNA is used where a suspect is identified, the sample of suspected is compared to the evidence that is found at the crime scene. If the DNA sequence of the suspect is similar to the DNA, that is found at a crime scene. It means the crime is done by that person.
<span>Avery Identified through a qualitative test that DNA was present. Through a chemical test he found that the make up was DNA. Through enzyme testing Avery found that only DNA degradation stopped transforming.</span>
