DNA analysis | NMDCAT 2021

Hi Everyone! Welcome To My Channel "Ali Academy Biology Lectures" About This Video ........................ In This Video Lecture You Will Learn Basic Concept Of DNA Analysis The entire genome of an individual can be subjected to DNA inger printing, a process described in Fig. 23.6. The genome is treated with restriction enzymes, which results in a unique collection of diferent sized fragments. Therefore, restriction fragment length polymorphism (RFLPs) exists between individuals. During a process called gel electrophoresis, the fragments can be separated according to their lengths (molecular they appear as a smear. However, the use of probes for genetic markers produces a weight or size), and the result is a number of bands that are so close together that distinctive pattern that can be recorded on X-ray ilm. The DNA from a single sperm enough to identify a suspected rapist. Since DNA PCR ampliication and analysis can be used (1) to diagnose viral infections, genetic is inherited, its inger print resembles that of one’s parents. DNA inger printing and F2 successfully identiied the remains of a teenager who had been murdered eight years before because the skeletal DNA was similar to that of the parent’s DNA. of the victim.Therefore suspect 1 is the culprit. The suspect 2 and 3 are not. disorders, and cancer (2) in forensic laboratories to identify criminals; and (3) to The arrows on left side show common bands between mother and child while those on DNA from both of his parents. Obviously F1 sequence DNA taken from a 76,000 years old mummiied human braiti and from a 17 Fig. 23.7 (b) shows a case of disputed parenthood. Two persons F1 determine the evolutionary history’ of human population. It has been possible to is not the real father. his parents. Arrows indicate that some bands in him are like his father, some like his from murderer’s skin and hair, and from three suspects blood. Can you compare them cells from underneath her nails. They prepared DNA inger prints from blood of victim, for speciic DNA sequence and tell who is in guilty and who is not? The suspect 1 has claim to be the father of child C, whose mother’s inger print is given under M. The child has received Fig. 23.7(c) shows DNA inger prints which have been presented as forensic evidence. A parents. child’s inger print with that of his parents. The child has received DNA from both of mother. Some bands are. however, unique to him, which do not match with any of the criminal on a deserted place assaulted a woman. She scratched his face in her defence right show common bands between the father and the child. In Fig. 23.7 are given some DNA inger prints. The igure 23.7 (a) shows comparison of but he murdered her and ran away. Forensic scientist recovered murder’s hair and skin inger prints, which is similar to linger print from skin cells taken from underneath nails to 20 million years old plant fossil following PCR ampliication. About This Channel..................... I make these videos cause I love to draw and connect the complexity of science and medicine into art. I'm not saying. I'm 100% correct in all my videos, but I do try to obtain the information from credible sources. One-stop destination for all biology lectures. _ students in class 11, 12 or appearing for competitive medical exams ( NMDCAT ) will find it very beneficial _ The videos are categories under various heading to make the students life simplified Visit My Other Channel Playlist .....................
