hello!!
here is yor anser.
DNA, short for deoxyribonucleic acid, is the molecule that contains the genetic code of organisms. This includes animals, plants, protists, archaea and bacteria.
DNA is in each cell in the organism and tells cells what proteins to make. Mostly, these proteins are enzymes. DNA is inherited by children from their parents. This is why children share traits with their parents, such as skin, hair and eye color. The DNA in a person is a combination of the DNA from each of their parents.
Part of an organism's DNA is "non-coding DNA" sequences. They do not code for protein sequences. Some noncoding DNA is transcribed into non-coding RNA molecules, such as transfer RNA, ribosomal RNA, and regulatory RNAs. Other sequences are not transcribed at all, or give rise to RNA of unknown function. The amount of non-coding DNA varies greatly among species. For example, over 98% of the human genome is non-coding DNA, while only about 2% of a typical bacterial genome is non-coding DNA.
Viruses use either DNA or RNA to infectorganisms. The genome replication of most DNA viruses takes place in the cell's nucleus, whereas RNA viruses usually replicate in the cytoplasm.

DNA is a protein based double helical structure with a sugar backbone and phosphate group. It stands for Deoxyribose Nucleic Acid and hence, is acidic due to the presence of phosphate groups.
DNA is a double helical structure due to the interaction between the two strands. The hydrogen bonds form salt bridges between two parts (obviously one partially positive and the other partially negative) and hence give the DNA its structure. This conformation (i.e. structure) is more stable. Hence, DNA is also more stable than RNA which is only a single helix.
DNA has active components called genes which carry all the genetic information for hereditary progression of traits to occur. Hence, it is very important in the growth and functioning of the body as it produces and supervises all the non-essential (those which can be synthesized in the body) proteins and body cells (their structure etc).
My information regarding the topic is still very meagre. Hope this helped you.
