DNAor 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, orDNAfor short.

deoxyribonucleic acid

deoxyribonucleic acid is correct answer

DNA means Deooxyribonucleic acid is a type of nucleic acid present in cell..it stores genetic information..and are responsible for storage and transfer of genetic characters i.e.responsible for heredity.

deoxyribonucleic acid, a self-replicating material which is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.

Deoxyribonucleic acid(/diːˈɒksɪˌraɪboʊnjuːˌkliːɪk,-ˌkleɪ-/(listen);[1]DNA) is a molecule composed of two chains that coil around each other to form adouble helixcarryinggeneticinstructions for the development, functioning, growth andreproductionof all knownorganismsand manyviruses. DNA andribonucleic acid(RNA) arenucleic acids; alongsideproteins,lipidsand complex carbohydrates (polysaccharides), nucleic acids are one of the four major types ofmacromoleculesthat are essential for all known forms oflife.

The two DNA strands are also known aspolynucleotidesas they are composed of simplermonomericunits callednucleotides.[2][3]Each nucleotide is composed of one of fournitrogen-containingnucleobases(cytosine[C],guanine[G],adenine[A] orthymine[T]), asugarcalleddeoxyribose, and aphosphate group. The nucleotides are joined to one another in a

DNA contains four basic building blocks or ‘bases’:adenine (A),cytosine (C),guanine (G) andthymine (T).

The order, or sequence, of these bases form the instructions in the genome.

DNA is a two-stranded molecule.

DNA has a unique ‘double helix’ shape, like a twisted ladder.

Each strand is composed of long sequences of the four bases, A, C, G and T.

The bases on one strand of the DNA molecule pair together withcomplementary bases on the opposite strand of DNA to form the ‘rungs’ of the DNA ‘ladder’.

The bases always pair together in the same way,A with T, C with G.

Each base pair is joined together byhydrogen bonds

Each strand of DNA has a beginning and an end, called 5’ (five prime) and 3’ (three prime) respectively.

The two strands run in the opposite direction (antiparallel) to each other so that one runs 5’ to3’ and one runs 3’ to5’, they are called the sense strand and the antisense strand, respectively.

The strands are separated duringDNA replication

This double helix structure was first discovered by Francis Crick and James Watson with the help of Rosalind Franklin and Maurice Wilkins.

The human genome is made of 3.2 billion bases of DNA but other organisms have different genome sizes.

DNA means deoxyribonucleic acid .It act as genetic material in our body

Deoxyribonucleic acid, or DNA, is a biologicalmacromoleculethat carries hereditary information in many organisms. DNA is necessary for the production of proteins, the regulation, metabolism, and reproduction of thecell. Large compressed DNA molecules with associated proteins, called chromatin, are mostly present inside the nucleus. Some cytoplasmic organelles like themitochondriaalso contain DNA molecules.
