what is DNA?

Question

i know its a really long word, but what is it?

Answer 1

DNA is deoxy-ribose nucleic acid. its made up of different parts called thymine, guanine, cytosine, and adening. its what stores all the information that makes you look like what you look like today. everybodys DNA strand is different

Answer 2

Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and functioning of living organisms. DNA is a long polymer of simple units called nucleotides, which are held together by a backbone made of sugars and phosphate groups. This backbone carries four types of molecules called bases, and it is the sequence of these four bases that encodes information. The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code. To read the genetic code, cells make a copy of a stretch of DNA in the nucleic acid RNA. These RNA copies can then be used to direct protein biosynthesis, but they can also be used directly as parts of ribosomes or spliceosomes.

Answer 3

Quoted word for word:

"DNA) is a nucleic acid that contains the genetic instructions for the development and functioning of living organisms. All living things contain DNA genomes. A possible exception is a group of viruses that have RNA genomes, but viruses are not normally considered living organisms.

The main role of DNA in the cell is the long-term storage of information. It is often compared to a blueprint, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules.

The DNA segments that carry genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the expression of genetic information."

In eukaryotes such as animals and plants, DNA is stored inside the cell nucleus, while in prokaryotes such as bacteria, the DNA is in the cell's cytoplasm. Unlike enzymes, DNA does not act directly on other molecules; rather, various enzymes act on DNA and copy its information into either more DNA, in DNA replication, or transcribe and translate it into protein. In chromosomes, chromatin proteins such as histones compact and organize DNA, which helps control its interactions with other proteins in the nucleus.

Answer 5

Deoxyribnucleic acid.
Basically, it's a molecule in your cells that determines protein production. One DNA molecule is made out of a sugar called ribose, which contains 5 carbon atoms, as well as a nitrogenous bases (thymine, adenine, guanine, or cytosine) and a backbone made of phosphate. The DNA molecule is in the shape of a double-helix, meaning there are two strands that twist around each other to form what looks like a ladder.

Answer 7

Short answer: it's the coding for how to build an organism or life-form. It tells how to build what to get a person, plant, or other type of animal. Think of your body as a blank hard-drive. DNA is the program that tells the computer what to put on the hard-drive.

Answer 8

DNA is a material in a cell's nucleus that stores coded information about how an organism will grow and develop
that a very simple way of putting it
