A spectrophotometer can be used to know if a sample is DNA or RNA.
DNA has an absorbance maximaat 260nm, whereas RNA has an absorbance maxima at 280nm.
By looking at which one of these two wavelengths the sample is more excited, one can determine if the sample is DNA or RNA.
Gel electrophoresis separates DNA fragment on the basis of their size. In DNA fingerprinting or DNA typing given sample is cut up with restriction enzymes and run through electrophoresis and results are analyzed to check for DNA polymorphism between the given sample and a sample form suspect. In nutshell gel electrophoresis is boon for the people in forensics.

Not without violating the conditions of your parole. You must comply with any lawful order given by your parole officer, and collecting a DNA sample, is a lawful order.

To locate the nucleotide sequence within a DNA or RNA sample, one can use a technique called DNA sequencing. This process involves determining the order of nucleotides in the sample, which can be done using various methods such as Sanger sequencing or next-generation sequencing technologies. These techniques allow researchers to read the sequence of nucleotides in the DNA or RNA sample, providing valuable information for genetic analysis and research.
In most of the countries the police are not allowed to get your DNA sample without the permission of the court.
A technique called polymerase chain reaction (PCR) is used to create a large sample of DNA from a small sample. PCR amplifies specific regions of DNA by making millions of copies, allowing for further analysis and testing on the amplified DNA.
* you have to, or they will proclaim you guilty since you won't give it to them you have to, or they will proclaim you guilty since you won't give it to them * You would be charged with 'failing to provide a specimen' or perhaps 'witholding evidence', whether you refused to give a urine/DNA/breath sample.
Everyone? Except people who are imaginary, no DNA for them.
Yes, because each DNA is unique and and the scientist can just match the DNA up with andother DNA.
what equipment do DNA use to analyzle sample?
A sample of the girl's DNA led to the breakthrough in the case.
