Abstract Background DNA profiling has proven to be a valuable technique for identification of individuals in crime. Currently, the technique targets several short tandem repeat (STR) regions in human genome. However, increasing number of samples submitted for STR analysis may lead to delays due to the limited number of experienced analysts who might be available at any given moment and the time taken to complete lengthy DNA profiling procedures. This study was conducted to test the specificity, repeatability, reproducibility and robustness of Investigator® 24plex GO! kit for genotyping of reference samples submitted to the Royal Malaysian Police Forensic DNA Laboratory for DNA database. Material and methods In this study, Investigator® 24plex GO! kit was used to directly amplify STR loci from buccal swab cell of reference samples that had previously been STR typed using GlobalFiler™ Express kit. Capillary electrophoresis was carried out on a 3500xL Genetic Analyser using POP-4® Polymer. Amplified products were assigned to particular STR alleles using the GeneMapper ID-X version 1.4 software. Results Our study shows that STR profiles generated using Investigator® 24plex GO! gave concordance results with those previously obtained using the GlobalFiler™ Express kit. In addition, quality sensors included in the kit are of particular importance for determining the effectiveness of the PCR reaction and help to indicate the nature and quantity of DNA template for PCR amplification. Conclusion The Investigator® 24plex GO! kit is reliable for STR typing of reference samples.

Ethnic Appearance

This article explores the place of ‘ethnicity’ in the operation, management and contestation of the UK National DNA Database (NDNAD). In doing so, it examines the limitations of bioethics as a response to political questions raised by the new genetics. The UK police forensic database has been racialised in a number of distinct ways: in the over-representation of black people in the database population; in the classification of all DNA profiles according to ‘ethnic appearance’; in the use of data for experiments to determine the ethnicity of crime scene DNA; and in the focus on ethnicity in public debate about the database. This racialisation presented potential problems of legitimacy for the NDNAD but, as the article shows, these have been partly neutralised through systems of ethico-political governance. In these systems of governance discussion of institutional racism has been postponed or displaced by other ways of talking about ethnicity and identity.

<p>ABSTRAK</p><p>Upaya untuk menurunkan kandungan nikotin merupakan salah satuprioritas utama penelitian tembakau. Nikotin adalah senyawa alkaloidutama berpotensi dikonversi menjadi senyawa nor-nikotin yang bersifatkarsinogen. Gen PMT sebagai penyandi enzim putresin n-metiltransferase(PMT) dan gen QPT - penyandi enzim quinolinat fosforibosiltransferase(QPT) merupakan dua gen kunci yang berperan penting pada proses bio-sintesis nikotin. Penelitian ini bertujuan untuk mengisolasi potongan genPMT dan QPT asal tembakau lokal Indonesia, mengkarakterisasi danmenganalisis runutan DNA-nya. Tahapan penelitian dimulai dengan me-rancang primer degenerate berdasarkan informasi yang ada di pangkalandata Bank Gen NCBI (National Centre for Biotechnology Information),mengamplifikasi PCR menggunakan templat DNA genomik tembakaulokal cv. Sindoro1, mengklon potongan DNA hasil PCR dan menentukanrunutan DNA-nya. Hasil penelitian menunjukkan dari dua belas pasangprimer degenerate yang dirancang, hanya dua pasang primer yang meng-hasilkan potongan DNA hasil amplifikasi PCR, yaitu pasangan primerPMt-7 (F &amp; R) untuk gen PMT dan primer QPt-3 (F &amp; R) untuk gen QPT.Setelah dilakukan penentuan runutan DNA-nya, amplikon yang didapatdari hasil PCR dengan pasangan primer PMt-7 sebesar 1418 bp, sedangkanuntuk primer QPt-3 sebesar 205 bp.

Nicotine is the main alcaloid compound that potentiallycould be converted into a carcinogenic compound (nor-nicotine). The PMTgene encoding putrescine N-methyl transferase (PMT) and the QPT gene -encoding quinolinate phosphoribosyl transferase (QPT) are the two keyenzymes involved in nicotine biosynthesis. The objectives of this researchwere to isolate PMT and QPT gene fragments originated from Indonesianlocal tobacco, to characterize, and to analyze their DNA sequences. Theresearch activities included: degenerate primer design based oninformation available in the GenBank DNA Database NCBI (NationalCentre for Biotechnology Information), PCR amplification usingdegenerate primer and genomic DNA template of a local tobacco cv.Sindoro1, clone the PCR amplified products, and determine their DNAnucleotide sequences. Results of the experiment indicated that from 12degenerate primer pairs synthesized, only two were able to yield positivePCR amplified products. These primer pairs were PMt-7 (F &amp; R primers)for PMT and QPt-3 (F &amp; R primers) for QPT. After DNA sequencing, theamplified DNA product amplified using PMt-7 degenerate primer pairswere 1418 bp, while that using QPt-3 primer pairs were only 205 bp.Nucleotide sequences of PMT or QPT gene fragments originated fromlocal tobacco cv. Sindoro1 showed a high nucleotide sequences identity ascompared to that of the respective genes from other tobacco species thatwere available in the GenBank DNA Database NCBI.</p><p>Key words: PMT gene, QPT gene, nicotine biosynthetic pathways, DNAsequencing, PCR amplification, degenerate primer</p>

In terms of crime scene investigations by means of forensic DNA-analyses, burglaries are the number one mass crime in Switzerland. Around one third of the DNA trace profiles registered in the Swiss DNA database are related to burglaries. However, during the collection of potential DNA traces within someone’s residence after a burglary, it is not known whether the sampled DNA originated from the perpetrator or from an inhabitant of said home. Because of the high incidence of burglaries, crime scene investigators usually do not collect reference samples from all the residents for economical and administrative reasons. Therefore, the presumably high probability that a DNA profile belonging to a person authorized to be at the crime scene ends up being sent to a DNA database for comparison, has to be taken into account. To our knowledge, no investigation has been made to evaluate the percentage of these non-perpetrator profiles straying into DNA databases. To shed light on this question, we collected reference samples from residents who had been victims of recent burglaries in their private homes. By comparing the profiles established from these reference samples with the profiles generated from trace DNA, we can show that the majority of the DNA samples collected in burglary investigations belong to the residents. Despite the limited number of cases included in the study, presumably due to a crime decline caused by the pandemic, we further show that trace DNA collection in the vicinity of the break and entry area, in particular window and door glasses, is most promising for sampling perpetrator instead of inhabitant DNA.
