The Steps of DNA Replication
The creation of a new human being is an amazing process, and it begins with the transference of genetic information.
1. An egg is fertilized by a sperm, beginning the process.
2. The chromosome pairs in both the egg and sperm are split, with one half of the pairs from both the mother and father combining to form a full chromosome pair.
3. Each cell unravels, decodes, and replicates the chromosomal DNA, which are the building blocks of every other cell in the body.
4. This continues for each cell that the body ever makes until the body dies.
How DNA Works
Even though it is such an important molecule, DNA was slow to be discovered and understood. Scientists and researchers have only really begun to understand hereditary traits in the past century or so. You can think of DNA as the blueprint for each one of the cells in your body. Certain parts of your internal cellular structures are dedicated to unraveling and interpreting your DNA so that your body can produce everything from skins cells to heart cells. The long strings of code that DNA keeps locked into its double helix structure contains all the information your body needs to make you who you are.
Using Science to Gain Valuable Information
This guide from gtlDNA.com helps you interpret the information locked away in a person’s genetic code is powerful. Although commercially available DNA kits are a relatively recent phenomenon, they have been used extensively to:
· Discover suspected relatives
· Learn of one’s own ancestry
· Determine paternity
· Investigate infidelity
· Ascertain valuable personal genetic information
The Effectiveness of testing for Specific Genetic Markers
Each person has distinctive DNA, much like fingerprints. No two people have the same DNA, not even identical twins. The reason for this is because of the random combination of genetic material from the mother and father, as well as numerous “copy errors” that naturally occurs in DNA. Since DNA is distinctive, it is used with a great deal of success in a legal capacity. Using DNA evidence can effectively prove the presence of a specific individual. A take-home DNA test can be used to gain peace of mind about a child’s paternity, or even investigate partner infidelity.
DNA Tests Admissible in Court
There are a number of DNA tests that are allowed in court to assist individuals in legal matters. In child custody and support cases, paternity tests are often required. Since paternity tests are such common requests, there are a number of very affordable take-home DNA kits available for online purchase. If you have been instructed to perform a paternity test or a different type of DNA test by a legal official, make sure that you are adhering to the minimum standards.
Getting the Best Information Possible
Most DNA tests only look for as little as 5 or 9 specific genetic markers. This is adequate for the most basic of tests, and these tests are not conclusive enough for legally binding situations. Choosing a DNA laboratory service that tests for 13 or 16 genetic markers is by far the best choice. Being able to compare more genes makes results much more accurate. If you are getting tested to look for predisposed hereditary disorders, you should choose a more comprehensive test.
Ordering the Right DNA Kit
The science of genetics is detailed and complex. There are three main types of DNA tests. This means that picking the correct test for your situation makes all the difference. The tests are built around the principal of maternal or paternal heredity. Since the male always gives a Y chromosome, it is a very reliable means of tracking heredity. If you have any questions about which test you need, ask an expert.
There are all sorts of reasons why you might want to have your genes analyzed. If you would like to know more about your DNA, order a test through an online DNA testing lab.
