What is DNA simple words?
DNA or deoxyribonucleic acid is a long molecule that contains our unique genetic code. Like a recipe book it holds the instructions for making all the proteins in our bodies. Your genome? is made of a chemical called deoxyribonucleic acid, or DNA for short.
What does DNA mean in simple terms?
Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries genetic information for the development and functioning of an organism. DNA is made of two linked strands that wind around each other to resemble a twisted ladder — a shape known as a double helix.
What is DNA simple explanation?
DNA stands for deoxyribonucleic acid . It contains units of biological building blocks called nucleotides. DNA is a vitally important molecule for not only humans but also most other organisms. DNA contains our hereditary material and our genes, the things that make us unique.
What is a simple explanation of DNA?
The molecule inside cells that contains the genetic information responsible for the development and function of an organism. DNA molecules allow this information to be passed from one generation to the next.
What is DNA in full words?
DNA is an abbreviation of deoxyribonucleic acid. It is a type of macromolecule (a very large molecule—one composed of hundreds of thousands of atoms) known as a nucleic acid. Nucleic acids are made of smaller molecules known as nucleotides, which are made of a phosphate, a sugar, and nitrogen bases.
Why is DNA important for life?
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
How is DNA used in everyday life?
In all living things, DNA is essential for inheritance, coding for proteins, and providing instructions for life and its processes. DNA dictates how a human or animal develops and reproduces, and eventually dies. Human cells normally contain 23 pairs of chromosomes, for a total of 46 chromosomes in each cell.
What are some fun facts about DNA?
