What do you understand by DNA?

Answer 1

It stands for Deoxyribo Nucleic Acid..It is the material inside the nucleus of cells that carries genetic information for growth, development, and replication of a cell.

Answer 2

DNA- deoxyribonucleic acid is a double helical structure, constituting the basic genetic make up of any living being i.e. plants & animals. it contains nucleotide bases (nitrogen containing bases) adenine, guanine, thymine and cytosine. These are paired as AT & GC in a ladder shape, only twisted like a double helix. The DNA is the basis of life and determines the sex of all individuals. DNA has a different pattern for all individuals and the pattern of DNA structure is unique to every single individual on this earth. Structure of DNa can be determined by electrophoresis, where bands of DNA appear as distinct lines, much like a chromatogram.
The structure of DNA was first elucidated by Watson and Crick, which is widely accepted as basis for all studies today.

Answer 3

That evolution is real. That all cancers are genetic. That medicines can be specifically targeted in individuals based on their genetic makeup. That we are very genetically similar to all other mammals. That certain inherited diseases are caused by problems in DNA functioning. That aging is based on the "tail ends" of chromosomes (at least in part). The actual list of what is known because of DNA would fill libraries - this is just a tiny partial list.

Answer 4

dna-deoxyribonucleicacid. it is genetic material with out which transver of ccharacters doesnot occur.it has deoxyribo sugar, phosphate group, nitrigenous bases. it relicate and transver to next generation.it undergo transcription forms RNA which inturn translate to form polypeptide chain.

Deoxyribonucleic acid: Carrier of the genetic information; structural plan for proteins; the DNA consists of linearly linked nucleotides, whose sequence forms the hereditary information Illustration 1: The DNA, the deoxyribonucleic acid, consists of two strands of linked nucleotides with one of the four bases adenine (A), thymine (T), guanine (G) and cytosine (C). One oxygen atom is missing in the sugar content of the nucleotide - thus the prefix "deoxy". ...

The molecule that encodes genetic information. DNA is a double-stranded molecule held together by weak bonds between base pairs of nucleotides. The four nucleotides in DNA contain the bases: adenine (A), guanine (G), cytosine (C), and thymine (T). In nature, base pairs form only between A and T and between G and C; thus the base sequence of each single strand can be deduced from that of its partner.

Deoxyribonucleic acid (DNA) or deoxyribose nucleic acid is a nucleic acid that contains the genetic instructions specifying the biological development of all cellular forms of life (and many viruses). DNA is often referred to as the molecule of heredity, as it is responsible for the genetic propagation of most inherited traits. During reproduction, DNA is replicated and transmitted to the offspring.
