DNA Profiling Test in India - A Revolutionized Tool for Encoding Your Genes

-
DNA is an abbreviation for DeoxyriboNucleic Acid. It encodes genetic information necessary for the functioning & development of the organisms. In eukaryotes (humans, animals, & plants), DNA is stored in the nucleus and in some organelles (mitochondria or chloroplasts). While prokaryotes (bacteria) store it in their cytoplasm. This double helix model holds the genetic makeup of every human and can be used to trace their ancestry and ethnicity. While DNA has many benefits, a striking area of importance is its usefulness for profiling or what is known as DNA fingerprinting. DNA Profiling is a molecular technique used to collect genetic information about the individual for parentage testing, criminal and forensic investigations. DNA fingerprinting history began with Sir Alec Jeffrey's discovery of the minisatellite DNA in 1984.



Methods Used for DNA Profiling

How does DNA profiling work? Our chromosomes contain markers in the DNA sequence that repeat multiple times. The number of repetitions differs from person to person at each marker. Furthermore, we all have two copies of each marker. One is inherited from the mother and another from the father. To perform DNA profiling/fingerprint analysis, researchers need a biological sample. It can be a buccal swab, hair, saliva or blood sample, or other available tissue.

There are several methods for DNA Profiling Tests, which are:
  1. Restriction Fragment Length Polymorphism (RFLP) test is the oldest and the most time-consuming method, which provides great results, but can't be used for parentage testing. This method used restriction enzymes to cut DNA into pieces.
  2. With advancements in technology, DNA fingerprinting analysis got evolved. The invention of PCR (polymerase chain reaction) technology increased the speed of the DNA fingerprinting process. It creates thousands of copies of sequences within a limited time.
  3. The discovery of STRs ushered in a new era in DNA fingerprinting (Short Tandem Repeats). They are DNA sequences that are only two to four nucleotide pairs long and generate highly unique patterns akin to minisatellite DNA. It is the most commonly used DNA profiling method for forensic identification.

Your Way Out to Forgeries - Signature Verification Test in India

-
Image
Signatures are a unique form of identification that is used to authenticate documents and transactions. However, signature forgery is a common form of fraud that can have serious consequences. Signature verification tests are used to ensure that signatures on important documents are genuine and have not been forged. We provide signature verification tests in India, offering accurate and reliable results. Signature Verification Test: An Overview A signature verification test is a forensic analysis that is used to determine whether a signature is genuine or forged. The test involves a comparison of the questioned signature with a known or reference signature. The reference signature is obtained from a verified source, such as a previous document or a sample signature provided by the individual whose signature is being verified. The signature verification process typically involves the following steps Collection of known and questioned signatures: Known signatures are collected...

Paternity Test Cost in India- A Comprehensive Overview

-
Image
DNA testing is most typically used to prove the genetic relationship between the involved participants. It can be done for many purposes, like immigration, organ transplants, child swaps, etc. Every person passed down their DNA from their biological parents, half from their biological father & half from their biological  mother. One of the most common DNA test is the paternity DNA test. Paternity testing offers accurate & dependable results, significantly deciding uncertainties related to parentage. This article discusses several factors influencing the cost of paternity DNA testing in India. Factors Influencing Cost Several factors influence the cost of paternity DNA testing: Type of Test:  The most common paternity test types include home DNA testing kits and legal DNA tests. Home kits are typically less costly but may have limitations regarding legal admissibility and precision. Legal DNA testing is often more comprehensive and can be used legally. S...
