The nature of DNA, obtained by different conventions and exposed to different capacity conditions can be decided by contrasting the PCR enhancement profiles.


The most normally utilized strategy that can be gotten by practically any research facility is RAPD . Rapid amplification polymorphic DNA (RAPD) is a PCR based procedure for recognizing genetic variations.


 It includes the utilization of a single, arbitrary primer in a PCR response, coming about in the enhancement of numerous discrete DNA products. 


The strategy was grown freely by two

various research centers (Williams et. al., 1990; Welsh and McClelland, 1990) and called RAPD and AP-PCR (Arbitrary prepared PCR) separately. This system recognizes nucleotide sequence polymorphisms in a DNA amplification based measure utilizing just a solitary primer of arbitrary nucleotide

arrangement. 


In this process, a single types of primer ties to the genomic DNA at two unique positions 

on inverse strands of the DNA format. On the off chance that these preparing destinations are inside an amplifiable distance of

one another, a discrete DNA item is created through thermocylic enhancement. 


The polymorphisms between individuals result from arrangement differences in either of the primer binding sites and are noticeable as the presence or nonappearance of a specific RAPD band. Such

polymorphisms hence act as the dominant hereditary markers.

To detect genetic syndromes, two groups of tests are available, molecular and cytogenetic tests. After the identification and definition of mutations, diagnostic methods or tests can be used to find them using techniques such as allele-specific oligonucleotide hybridization, allele-specific amplification, ligation, primer extension and the artificial introduction of restriction sites.

CFTR Gene Mutation Analysis

It leads to the production of thick, sticky mucus and can cause recurrent respiratory infections and impaired function of the pancreas. The CF gene mutation panel detects the common mutations in the cystic fibrosis transmembrane conductance regulator ( CFTR ) gene on chromosome 7 to screen for or diagnose CF or to identify carriers of the disease. Cystic fibrosis is caused by a mutation in each of the two copies of the  CFTR  gene (one copy from each parent). Both copies (alleles) of this gene pair must be abnormal to cause CF. If only one copy is mutated, the individual is a CF carrier. Carriers do not generally have any CF symptoms, but they can pass their abnormal

NEURODEGENERATIVE DISEASES : AN OVERVIEW.

Neurodegenerative diseases represent a major threat to human health. These age-dependent disorders are becoming increasingly prevalent, in part because the  elderly  population has increased in recent years. Neurons are the building blocks of the nervous system which includes the  brain  and  spinal cord.  Neurons normally don’t reproduce or replace themselves, so when they become damaged or die they cannot be replaced by the body. Neurodegenerative diseases are incurable and debilitating conditions that result in progressive degeneration and / or death of nerve cells. This causes problems with movement (called  ataxia
