DNA Profiling – How You Can Do It

DNA profiling is basically a process by which certain DNA pattern, known as the Profile is collected from a person or a tissue sample.

Despite the fact that we all have our unique DNA, similarities might occur between two individuals. However, in some region, the disparities between the DNA of different people are very high; this is basically referred to as polymorphism. Every human on the planet inherited a unique pattern of polymorphisms from their parent. The DNA polymorphism is what is analyzed to gain insight into a given DNA profile.

The human DNA profile can be used in identifying the source of a DNA that is found at a crime scene or to test if two people are related. Below are some of the ways DNA profiling is used today.

  1. To identify the origin of body fluid that is found at a crime scene.
  2. To determine if two people are related
  3. To identify accident or disaster victims

In recent years a lot of people who were convicted of crimes they did not commit have been released. This is possible because of the DNA profiling. And it is been used in practically every industry today. For other uses on DNA profiling, such as in healthcare, you can read here: http://www.mapmygene.com/services/disease-susceptibility-test.

Short tandem repeats

The current techniques used in DNA profiling involve the use of polymorphism that is known as short tandem repeats. The Short tandem repeats is a region that consists of non-coding DNA that has repeats of the same nucleotide. The STRs can be found at different locations in the genetic loci in the DNA of a person.

DNA profile- what is it?

One of the most effective ways to produce a DNA profile is through the examination of STRs at ten or more genetic loci. These loci are usually located on different chromosomes.

A DNA profile can provide insight in determining if a DNA sample is a male or female, it can also tell who a particular genetic sample belongs to.

Next, we are going to discuss the step by step method on how you can create a DNA profile through the use of STR.

Step 1

Find a sample of DNA

DNA can be found in most of the cells in the body, including semen, body tissue and the white blood cell. DNA traces can also be gotten from body fluids like sweat and saliva. DNA can be found in the saliva as well as in body fluids because they contain epithelial cells.

At a crime scene, police officers and forensic scientists collect samples of DNA so as to locate a suspect. DNA can also be collected directly from a person’s mouth through the use of a mouth swab which is able to collect the cells in the inner cheeks.

Step 2

Extracting the DNA

Basically, DNA is wrapped by a nucleus of cells. In order to extract the DNA, you have to break these cells through the use of certain chemicals. When this is done, you will be able to isolate the DNA from other cell components.

Step 3

Copying the DNA

Most of the time only a very small amount of DNA is available for forensic analysis, so PCR is used to get enough DNA to make a complete profile.

Step 4

Find out the size of the STRs

The size of the STRs is determined through the use of a genetic analyzer.

Step 5

Check if there is a match.

The number of times a sequence is repeated in an STR is calculated to determine the size of the STRs. You can use the information from this to determine if a tissue sample is from a particular person.

What Is Foreign Worker Insurance?

Any firm that employs workers from outside the country must comply with the rule of the land. One major criterion being that foreign worker insurance must be in place. This is not at all dependent on designation or status. The coverage must be during the duration of employment. Let us look at the different types of insurance that are included in this vast domain.

Hospitalization as well as post operation costs. The company cannot to pass the cost onto employees; it must be borne by the employer. Most foreigners ensure that they have a working policy in their home. While abroad, the firm must ensure that any medical coverage – even dental care, is on the cards. Many senior level employees ensure that they get family insurance too.

Accident Insurance

Skilled and unskilled workers need to be covered the moment they land in a foreign country. In case of an accident during working hours or even after work hours, the employee is entitled to treatment. In case of a serious injury, all the costs will be borne by the insurance provider. If for any chance the employee is incapable of resuming duty because of a serious injury at work, he will be entitled to a suitable compensation along with free airfare back to his parent country.

Life Coverage

Companies that employ professionals from other nations have to provide life insurance coverage as a part of foreign worker insurance. Every employee must ensure that he reads the content of the offer letter, which provides him all the necessary details prior to joining a firm overseas. Laborers who work crazy hours are the ones who need maximum coverage in case they come into harm’s way. In case of death during employment in an overseas capacity, the insurance provider will reimburse the nominee prior to shifting the body back home.

Home Insurance Is Essential To Protect Your Home

Irrespective of whether you have settled your mortgage or purchasing a new house, you may have often wondered whether you really need to purchase home insurance or not. Your home is likely to be the most precious assets that you acquire during your lifetime. You and your investment can be protected by purchasing homeowners insurance in various ways.

Here are some of the most important reasons why you should contemplate purchasing homeowners insurance

Home insurance may be needed

When you have taken a mortgage, the lender may ask you to purchase homeowners insurance as a requirement. Prior to financing for the mortgage, your lender may usually ask you to give evidence that your house has been insured properly. The reason is that the mortgage company wants to be certain that there is protection for the financial investment it makes in your house in case your house gets damaged due to a fire or some other risks

But, when you have not availed homeowner’s insurance coverage, your lender could purchase coverage and then charge you for its cost. However, you should remember that the policy procured by your mortgage company is likely to be costlier than what you could have bought yourself and may provide limited coverage.

Protects not just your home but can do much more

Though standard homeowners’ coverage helps to protect your home, the scope of its coverage can go beyond your home’s physical structure. It can extend to your personal belongings that you have kept in the backyard of your home or medical bills when a guest sustains injury. While staying in your house, homeowner’s coverage may also include the following:

Guests: When a visitor gets accidentally injured while staying in your house, the guest medical protection clause of your policy can help you to pay their medical bills.

You as well as your family: When any of your family members or you are found liable for damaging the property of somebody accidentally or injuring somebody, coverage can be helpful for paying medical bills, legal fees, and related repair expenses.

Personal property: Such coverage can be helpful to pay for replacing specific belongings such electronics and furniture, which are damaged or robbed y a loss covered in the clause.

Your dwelling: When your house and other attached structures like a garage or decks get damaged by a peril that is covered, this policy can be helpful to pay repair costs.
