What is DNA introduction?
Deoxyribonucleic acid, more commonly known as DNA, is a complex molecule that contains all of the information necessary to build and maintain an organism. All living things have DNA within their cells. In fact, nearly every cell in a multicellular organism possesses the full set of DNA required for that organism.
How does the DNA work?
DNA's unique structure enables the molecule to copy itself during cell division. When a cell prepares to divide, the DNA helix splits down the middle and becomes two single strands. These single strands serve as templates for building two new, double-stranded DNA molecules - each a replica of the original DNA molecule.
What is DNA and its importance?
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 definition 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 short answer?
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 are the 3 functions of DNA?
DNA now has three distinct functions—genetics, immunological, and structural—that are widely disparate and variously dependent on the sugar phosphate backbone and the bases.

Where does DNA come from?
Your genome is inherited from your parents, half from your mother and half from your father. The gametes are formed during a process called meiosis. Like your genome, each gamete is unique, which explains why siblings from the same parents do not look the same.
What are the two main functions of DNA?
Solution : Replication and expression of genetic information in the form of polypeptides.
What are the 5 functions of DNA?

What is DNA made of?
DNA is a linear molecule composed of four types of smaller chemical molecules called nucleotide bases: adenine (A), cytosine (C), guanine (G), and thymine (T).

Who first discovered DNA?
Friedrich MiescherMany people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case. Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher.
What are types of DNA?
There are three different DNA types:A-DNA: It is a right-handed double helix similar to the B-DNA form. ... B-DNA: This is the most common DNA conformation and is a right-handed helix. ... Z-DNA: Z-DNA is a left-handed DNA where the double helix winds to the left in a zig-zag pattern.
What are the 3 functions of DNA?
DNA now has three distinct functions—genetics, immunological, and structural—that are widely disparate and variously dependent on the sugar phosphate backbone and the bases.
What is the power of the human genome?
Secrets, disease and beauty are all written in the human genome, the complete set of genetic instructions needed to build a human being. Now, as scientist and entrepreneur Riccardo Sabatini shows us, we have the power to read this complex code, predicting things like height, eye color, age and even facial structure -- all from a vial of blood. And soon, Sabatini says, our new understanding of the genome will allow us to personalize treatments for diseases like cancer. We have the power to change life as we know it. How will we use it?
Who invented the CRISPR-Cas9?
Geneticist Jennifer Doudna co-invented a groundbreaking new technology for editing genes, called CRISPR-Cas9. The tool allows scientists to make precise edits to DNA strands, which could lead to treatments for genetic diseases ... but could also be used to create so-called "designer babies.".
Can we observe molecules?
We have no ways to directly observe molecules and what they do -- but Drew Berry wants to change that. He demos his scientifically accurate (and entertaining!) animations that help researchers see unseeable processes within our own cells.
How does TED-Ed work?
TED-Ed is a web-based platform that offers video content that is primarily stored on YouTube so it can be easily shared and even integrated with Google Classroom.
How can TED Ed be made into a lesson?
Unlike a video found on YouTube, say, those on TED-Ed can be made into a lesson by adding follow-up questions that students are required to answer in order to show they have learned from watching. Lessons range across ages and cover a wide variety of topics, including both curriculum-based and off-curriculum materials.
