FORENSIC SCIENCES, NATIONAL FORENSICS SCIENCES UNIVERSITY, GOA CAMPUS INTRODUCTION DNA (Deoxyribose Nucleic Acid) is an essential molecule that present in all the living organisms which results in replication and growth of the organism it contains the genetic information which is passed generation after generation. DNA is made of phosphates, Deoxyribose sugar, nucleobases are formed into a double helix structure. The ability of DNA to carry information about the ancestors are applied in the Forensic science for crime solving. Touch DNA also refers to as ‘Trace DNA’ these are the less amount of DNA as 1ng that collected from a crime scene which may transferred from the skin cells of fingerprints because of handling or touching some object and the collected DNA is used to sequencing of gene STR(Short Tandem Repeats) analysis. Less amount of sample is only required. METHODOLOGY The process begins with ...

Pollen is generally described as the fine powdery substance that is released by the male part of a flower or flowering plant and consists of tiny grains that consist of a male gamete that can fertilise a female ovule, and all of this would, under the right circumstances, eventually lead to the production of a whole new plant.[1] The niche of forensic palynology comes into the picture as the study of pollen, spores, or other acid-resistant microscopic plant bodies and using them in criminal investigations. [2] Pollens are dispersed as part of a plant's reproductive propagation and therefore are dispersed through the wind, water, pollinator insects/animals, or even within themselves. There are a few ways one could use it in a forensic setting. They can be found on the victims and suspects' clothing, shoes, and skin when one either comes in contact with these plants/flowers or has moved through the soil where the pollens have been...
