It is a major understatement to say that cell replication is a complex activity. Generation of a new cell really is like “starting over,” but this beginning is a bootstrap operation. DNA Polymerase is key to getting from one cell … Continue reading DNA Polymerase: What is it & What Does it Do?
What is the function of sugar in DNA? DNA is one of the integral building blocks of life. It’s what makes you who you are on the most fundamental level. Strings of nucleotides form together in numerous different combinations, no … Continue reading What is the function of sugar in DNA?
In the past few decades, DNA testing through DNA samples has grown tremendously with technological and medical advancements. DNA is commonly found on items that are physically touched such as clothing, drink bottles, hats, headphones, postage stamps, and tissues. To … Continue reading The Ins and Outs of DNA Samples
An ancestry DNA test uses a saliva sample to determine which areas of the world your DNA can be traced back to. DNA kits have become very popular during the last few years. This has led to many people having numerous questions. You may be wondering if your genetic information will be used for research or sold and how this impacts your privacy. You may also be concerned regarding the accuracy of this test or have numerous additional questions. The first thing you must realize is the question of your DNA is complex and there may not be a simple answer. The majority of people in the world have DNA from numerous different regions. You may perceive this combination as unique or you may see it is odd. Either way, you need to be open and prepared for a surprise. Continue reading “Ancestry DNA Tests: How Accurate Are They?”
DNA, also known as Deoxyribonucleic acid, is a material too tiny for the naked eye to see that exists in abundance in the human body. Billions of such cells hold important information about us. In Gregor Mendel’s research in 1866 was some of the first to explore why physical similarities are inherited. Studies in the field of genetics would continue, but American biologist and British physicist James Watson and Francis Crick’s discoveries about DNA are considered the most game changing in understanding the physical makeup of DNA as well as its functions. Anyone who has seen a TV show in which detectives are gathering evidence at a crime scene know how valuable DNA is in helping to identify someone, but what role does it actually play in cell function? Continue reading “DNA Functions: An Overview of the Roles DNA Plays in Cells”

Understanding what causes diseases is not just crucial to creating treatments. It is also essential in the prevention of illness. While the focus has been on nature versus nature for many years, recent advances show that the solution may not always be so black and white.
Every cell in the body has a nucleus that contains 23 pairs of chromosomes. Each chromosome contains tightly packed DNA. The combinations of the varying lengths of DNA are what make up the genes. These genes are hereditary. They are used to instruct the synthesis of proteins that make up new cells in your body. Continue reading “Epigenetics: A Beginner’s Guide to How It Works [+ Examples]”
All living organisms, plants, animals, bacteria, and even some viruses, contain DNA. DNA is deoxyribonucleic acid, a molecule with two long chains that coil around each other creating a shape referred to as a double helix. Within the DNA is the material used for the genetic instructions of all life forms. DNA joins proteins, lipids, polysaccharides, and other nucleic acids as the four major macromolecules. These four macromolecules are found in all forms of life, and are necessary for life to exist. Continue reading “What catalyzes DNA Synthesis?”
