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

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
