The benefits of DNA profiling

The benefits of DNA profiling

 

 

 

The growing number of crime is one of the concerns of everyone right now. Luckily, we already have advanced equipment and processes in order to identify the criminals, assailants, and victims. The process done is actually called DNA profiling or some people also call it DNA typing or DNA testing. You have probably seen in in television shows, movies, or the news. Some people might think that it is only being used for this purpose, but actually there ways where we could use it. Many companies have offered such testing services for parents who wish to know more about the underlying traits of their children in order to better nurture their strengths, one such company is Mapmygene. Map my gene DNA profiling service  allows their clients to go through a series of checklist before the start of the test in order to first have a basic profile of their child’s traits

In article by Better Health, they will tell us more information about DNA profiling. Let us read below.

DNA Profiling

Genes make up the blueprint for our bodies, governing factors such as growth, development and functioning. Almost every cell in the human body contains a copy of the blueprint, stored inside a special sac called the nucleus. The estimated 23,000 genes are beaded along tightly bundled strands of a chemical substance called deoxyribonucleic acid (DNA). These strands are known as chromosomes. Humans have 46 paired chromosomes (half inherited from each parent), with two sex chromosomes that decide gender and 44 chromosomes that dictate other factors. Certain portions of DNA are unique to each individual. DNA profiling is a way of establishing identity and is used in a variety of ways, such as finding out whether twins are fraternal or identical. DNA samples are usually obtained from blood.

Uses of DNA profiling

Some of the uses of DNA profiling include:

  • paternity – to find out if the alleged father is actually the biological father of the child
  • twins – identical twins share the same genetic material, while fraternal (non identical) twins develop from two eggs fertilised by two sperm and are no more alike than individual siblings born at different times. It can be difficult to tell at birth whether twins are identical or fraternal
  • siblings – for example, adopted people may want to have DNA tests to make sure that alleged biological siblings are actually their blood brothers or sisters Read more here.

Wow! That was just a load of information about DNA profiling. We were able to read about the uses of DNA profiling, what DNA profile is, advantages of DNA profiling, limitations of DNA profiling, where to get help, and some things to remember. However there are some other benefits of DNA fingerprinting. Let us read about it through Paul Amold’s article below.

The Benefits of DNA fingerprinting

This article looks at the benefits of DNA fingerprinting in identification, forensics, and other lesser known uses of the technology such as how DNA profiling helps plants.

What Is It?

DNA fingerprinting (also known as DNA typing, DNA profiling, or genetic fingerprinting) is a person’s unique identifier, apart from identical twins. It is a scientific technique based on making a profile of specific portions of an individual’s DNA to establish identity, for example in paternity or maternity cases or in criminal investigations where biological material is left at a crime scene. Although the majority (99.5%) of our DNA is the same, there are short pieces, called microsatellites, which repeat many times in a person’s DNA. It’s the pattern of repeats that are different between individuals. Knowing these microsatellite DNA sequences is the basis of DNA profiling. Let’s examine what are the main benefits of DNA fingerprinting. Read more here.

Benefits in paternity tests and benefits in forensics were provided by Paul. So one benefit for paternity given is to determine whether the child is really your kid. Well, this only happens if you are unsure of your partner. On another note, let us see another thing that DNA profiling could do. Darya Gaysina will tell us about how DNA profiling could change how we educate our children.

Why genes matter: DNA profiling could change how we educate our children

Salman Rushdie recently caused controversy by bemoaning the lack of “rote learning” in schools. He spoke about the benefits of learning poetry by heart – a method many see as archaic and outdated in today’s classroom.

Despite the criticisms of Rushdie’s comments, the debate around the effectiveness of different learning styles in modern education is as active as ever – with many recognising that each pupil prefers a different learning style and technique.

This can of course make it hard for teachers to gear classes up for each individual’s preferred style of learning. Especially given that one style, such as social learning, can appear to be the exact opposite of another style, such as those who prefer a more solitary style of education.

Research shows that when it comes to learning style preferences or even A-level choice, they are pretty hard wired in each individual – with genes playing a large part in the process. And we know that genes can also shape our relationships with other people – whether they be parents, teachers or peers. Read more here.

So according to Darya, if we consider DNA differences among people in the future, educational genomics could personalize an approach to education. This could be a more effective way of teaching students because educational genomics could enable schools to accommodate different learning styles which suit different kinds of learners. That would be exciting and that could make a change. DNA profiling really provides more and more benefits as time goes by. Let us be thankful for having this to help us with our concerns today.
