what is dna

Dna or deoxyribonucleic acid is a long molecule that contains our unique genetic code. Deoxyribonucleic acid dna is a molecule that contains the biological instructions that make each species unique. It codes genetic information for the transmission of inherited traits.

Dna stands for deoxyribonucleic acid. Dna organic chemical of complex molecular structure found in all prokaryotic and eukaryotic cells. Dna or deoxyribonucleic acid is the hereditary material in humans and almost all other organisms.

A gene code for a polypeptide molecule where three nitrogenous bases sequence stands for one amino acid.

What is dna. Dna is a vitally important molecule for not only humans but for most other organisms. Dna contains four basic building blocks or bases. Dna is a very long molecule that contains the instructions for living things to build and maintain themselves. Dna is the genetic material which car ries all the hereditary information.

Dna along with the instructions it contains is passed from adult organisms to their offspring during reproduction. It holds the instructions for building the proteins that are essential for our bodies to function. Nearly every cell in a person s body has the same dna. Is made of a chemical called deoxyribonucleic acid or dna for short.

All organisms have their own unique strands of dna in each cell which forms a very long code known as their genome. Cells read the genes certain stretches of an organism s genome do certain things. In short dna is a long molecule that contains each person s unique genetic code. Most dna is located in the cell nucleus where it is called nuclear dna but a small amount of dna can also be found in the mitochondria where it is called mitochondrial dna or mtdna.

Genes are the small segments of dna consisting mostly of 250 2 million base pairs. It s made up of units of biological building blocks called nucleotides. These instructions are found inside every cell and are. Dna stands for deoxyribonucleic acid which is a molecule that contains the instructions an organism needs to develop live and reproduce.

The structure of dna was described in 1953 leading to further understanding of dna replication and hereditary control of cellular activities. Like a recipe book it holds the instructions for making all the proteins in our bodies. The function of dna is to store all of the genetic information that an organism needs to develop function and reproduce.
