We are all made up of DNA, and it’s amazing how much information is encoded in this simple molecule. In this blog post, we get to learn more about the wonders of our own DNA and how incredible it is. We learn why DNA looks like a double helix, that humans are genetically 98% identical, and have over 3 billion base pairs!
Why do we have DNA
DNA is the blueprint of life and it has a lot of people asking what exactly is it. DNA is one of the strongest molecules on Earth. On average, each person’s body has about 16 feet (5 meters) worth of DNA in their cells. DNA helps us survive because it dictates how our cells turn into organs, hairs, and even other human beings in the future. DNA is made up of nucleic acids that store information about our genes. DNA is found in the nucleus of cells and in most of the body’s cells. It is the instruction book for life, storing all the genetic instructions which enables us to develop and reproduce.
What is DNA
DNA, or deoxyribonucleic acid, is a long molecule that carries the genetic instructions used in the development and functioning of all living organisms. The total number of human genes is estimated at around 20,000. DNA stands for deoxyribonucleic acid, which is an essential molecule of the cell that carries genetic information. It is a long and complicated molecule, consisting of two strands that are twisted together to form a double helix shape. At its core, each one of these strands consists of a sugar-phosphate backbone with four types of bases attached to it: adenine (A), cytosine (C), guanine (G) and thymine (T).
How are DNA and proteins found in cells
DNA is a short sequence of genes on chromosomes. Proteins are the building blocks of cells. DNA is found inside cells and in the nucleus, where its function is to store genetic information and pass it down from parents to offspring. DNA is a complex molecule composed of four bases: adenine, guanine, cytosine, and thymine. Within this molecule is found the information required to create our cells and their functions.
DNA in different organisms
DNA is the key to life, and it’s a really important part of what makes you, you. Every single one of your cells contains genetic information that helps determine how your body functions. The more we learn about DNA, the more we realize how significant and rare it actually is. The way DNA structures look and function is different in every single living being on the planet. Some organisms have fewer base pairs, some have more; some have long strands of DNA, some shorter. There are a lot of mysteries about our DNA that we still don’t know the answer to–some of which we may never know. DNA has also been used to help us find solutions for some diseases like cancer.
Billions of cells and genomes
DNA is made up of billions of cells and each one is a blueprint for the human body. It is also responsible for regulating our development and controlling our functions. DNA is passed down from parents to children, and it’s possible for them to inherit traits from their DNA that were not present in their parents’ genes.
DNA is a genetic information storage system. It stores the information needed to create, replicate, and maintain all living cells within the human body. Cells store their DNA in a long chain of molecules called chromosomes. The human genome contains over three billion base pairs of DNA that are comprised of four bases: adenine, guanine, cytosine, and thymine.
