Forensic entomology is the study of insects found around the crime scene and are helpful for the estimation of time elapsed since death of a person i.e., post mortem interval (PMI). There are number techniques available for the identification of insect species and Random Amplified Polymorphic DNA (RAPD) is one of those. RAPD is a useful technique designed for the detection of sequence polymorph...

Dominant markers, such as RAPDs and ISSRs, have become popular in molecular studies in recent years. As an alternative to isozymes, these types of markers are especially attractive given their hypervariable nature, the vast numbers of loci that can be examined, and the small amount of fresh or dried material used per sample. However, one significant limitation is that in population genetic stud...

An overview on legal regulation, taxonomy, and botanical and chemical methods of analysis of marijuana are provided. Emphases are placed on the applications of the recently developed molecular biology methods to the identification and characterization of marijuana samples. Procedures for the extraction of plant DNA, DNA amplification, restriction analysis, and sequence analysis are reviewed. Th...

Recent DNA sequencing data have shown that J. flaccida var. flaccida, J. f. var. martinezii and J. f. var. poblana are polyphyletic taxa. Additional analysis using Random Amplified Polymorphic DNAs (RAPDs) analyses for J. durangensis, J. flaccida var. flaccida, var. martinezii, and var. poblana, J. jaliscana, J. monticola and J. standleyi revealed exactly the same pattern of relationships as se...

This study was accomplished to detect variation generated through eposure of fenugreek (trigonella foenum-graecum L.) seeds seven gamma irradiation doses (0,25,50,100,150,300 and 400) GY by using twenty RAPDs primers as molecular marker ,results indicated that OPA-14 ,OPC-19 OPH-01success in giving five treatments a unique fingerprint. Molecular size amplicon ranged between 2913 bp produced pri...
