The document discusses the challenges forensic scientists face in evaluating DNA and RNA sample collection methods, emphasizing the need for intact samples and proper storage. It highlights the use of Fourier Transform Infrared Spectroscopy (FTIR) as a technique to assess the integrity of DNA and RNA, particularly in bone samples where heat damage is a concern. FTIR spectroscopy estimates collagen bonds that correlate with bonds in DNA, aiding in the assessment process.

- 1. How can you find DNA and RNA on a scene using spectroscopy? How can you find DNA and RNA on a scene using spectroscopy? Solution It is a big challenge for Forensic scientists to evaluate the effectiveness of sample collection methods, the DNA and RNA samples should be intact and the storage should be proper accurate and reliable collecting of DNA for further analysis. Before the sample collection process is started, it is valuable to know if even the DNA or RNA is intact. Fourier transform infrared spectroscopy (FTIR) technique basically is a spectrometric teqnique to check the integrity of the DNA and RNA. This technique is usefull when we are dealing with the bone sample because excessive heat can damage the DNA. FTIR spectroscopy basically estimate the bond of collagen, which correlate with similar hydrogen and covalent bonds in DNA.
