Jan 3, 2024 · DNA, or deoxyribonucleic acid, is the molecule that makes up an organism’s genome in the nucleus of every cell. It consists of genes, which are the molecular codes for proteins – the building blocks of our tissues and their functions.

Bases pair through the arrangement of hydrogen bonding between the strands. The molecular basis for genes is deoxyribonucleic acid (DNA). DNA is composed of deoxyribose (sugar molecule), a phosphate group, and a base (amine group). There are four types of bases: adenine (A), cytosine (C), guanine (G), and thymine (T).

Many think of DNA as being fluid, dynamic, and ever-changing. But in fact, DNA is a static and stable molecule. Whether it’s from stone tools or the inside of ancient bones, it’s possible to collect DNA and study it—even after tens of thousands of years. An easy way to think of your DNA is like a blueprint to build a house. It conveys a lot of info...
DNA is the genetic material contained in every nucleus in your body. And while not every cell has a nucleus—and some cells have more than one—every nucleus has a complete DNA sequence. In each nucleus, DNA exists as a single (double-stranded) molecule. That is, a verylarge molecule. Human DNA is between two and three billion bases long. To put that...
So, how does DNA work to tell the cell what to make? DNA is made up of four basic building blocks called bases—adenine, thymine, guanine, and cytosine (abbreviated A, T, G, C, respectively). Here is where it gets really amazing. These four DNA bases repeat over and over again, but in a unique order that gives you your individuality. These bases (A,...
A gene is defined as the basic physical and functional unit of DNA. It’s nothing more than the instructions for the cell to make one or more proteins. As mentioned above, there are start signals and stop signals in your DNA. Simply put, a gene is everything between a single start signal and stop signal. It’s estimated that humans have approximately...
You can think of this codon code as a foreign language. It’s the language the cell needs to learn to read the DNA and to eventually make protein. In fact, geneticists even call this process transcription and translation—similar verbiage that’s used to describe human language. Let’s talk a little bit more in-depth about exactly how the cell can read...
Since the human genome was sequenced in 2003, scientists worked hard to figure out what it all means. It was initially thought that once we knew the order of every base in human DNA, huge breakthroughs in science and medicine would occur. But now, so many years later, it seems that more questions have arose than have been answered. Here’s why: It’s...
Apr 14, 2020 · Genetic testing involves examining your DNA, the chemical database that carries instructions for your body's functions. Genetic testing can reveal changes (mutations) in your genes that may cause illness or disease.
Genes are pieces of hereditary material that are passed from parents to offspring. Genes are part of cell structures called chromosomes. In multicellular organisms, chromosomes are found in the nucleus of the cell. Each of these chromosomes contains one, long molecule of DNA, or d eoxyribo n ucleic a cid.
