what is the full form of DNA?

It's D-Deoxyribose\n     N-Nucliec\n     A-Acid\n  It is present in the cells of all multicellular living beings.It has genetic codes due to which your body knows what to perform so that u would be alive.For instance,the dna in the cells of your stomach have the infortion that they should dissolve all the food that comes there and secrete gastric juice bla vla bla...\n   I am sure u understanf what is DNA.

DNA'S MOLECULAR IS VERY SMALL AND it's width is 20 angstrom.but dna is made by many helical pairs. a helical pairs's length is 34 angstrom.

The DNA is linked by the 4 bases G,C,A,T \nG and C pair together and A and T pair together they are held together by hydrogen bonds. G and C have 3 hydrogen bonds A and T have 2.\nThese form the double helix which is the DNA structure.

Deoxyribonucleic acid; a nucleic acid that consists of two long chains of nucleotides twisted together into a double helix and joined by hydrogen bonds between complementary bases adenine and thymine or cytosine and guanine; it carries the cell's genetic information and hereditary characteristics via its nucleotides and their sequence and is capable of self-replication and RNA synthesis.

new DNA...i dont know in new DNA but normal DNA is composed of sequences of Nucleotides which are molecules of sugar, Phosphate and a Nitric substance... sequences of predetermined Nucletides make genes...Humans have 46 chromosomes so we have 46 DNA Molecules....\n\nThis si complicated i could talk about 3 hours of DNA...why do u want to know that...this is advanced Molecular biology

DNA is made up of 3 units- \nDeoxy ribose sugar\nPhosphate\nNitrogen Base\n\nThe sugar and phospate form the backbone and the bases are attached to it at 90 degrees. Another complementary strand makes up this double helix. The bases of one strand are attached to those of the other by hydrogen bonds. \nAdenine//Thymine\nCytosine///Guanine\nThere's still a lot to describe- It's a 10 marks-question at University , you know.\n\nHey Sasha:\n"ALL OF THEM. each three purines (half steps) are called a genome and they code for one amino acid. "\n\nThe half steps, as you call them, could be either purines or pyrimidines. THEY ARE NOT CALLED A GENOME. Three nitrogen bases that code for one amino acid are called  TRIPLET CODONS. \nA genome is the whole genetic material of an organism.

DNA consists of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. The sequence of nucleotides determines individual hereditary characteristics.

DNA is composed of 4 bases: adenine (A), thymine (T), cytosine (C), and guanine (G). Uracil (U), is rarely found in DNA except as a result of chemical degradation of Cytosine, but the DNA of some viruses (notably PBS1 phage DNA) and RNA (Ribonucleic Acid), has Uracil instead of Thymine.\n\nEach base on one strand forms a bond with just one kind of base on another strand, called a "complementary" base: A bonds with T, and C bonds with G. Therefore, the whole double-strand sequence can be described by the sequence on one of the strands, chosen by convention. Two nucleotides paired together are called a base pair.\n\nIn a DNA double helix, two polynucleotide strands can associate through the hydrophobic effect and pi stacking. Which strands associate depends on complementary pairing. Each base forms hydrogen bonds readily to only one other base, A to T forming two hydrogen bonds, and C to G forming three hydrogen bonds. The GC content and length of each DNA molcule dictates the strength of the association; the more complementary bases exist, the stronger and longer-lasting the association, characterised by the temperature required to break the hydrogen bond, its melting temperature (also called Tm value))-.

you can read up on it here\n\nhttp://en.wikipedia.org/wiki/DNA\n\nbut even better would be to buy related books and take related courses

DNA is double stranded with Deoxyribose, and has the nucleic acids Guanine, Cytosine, Thyamine, and Adenine (GCTA)\n\nRNA is single stranded with ribose, and has the nucleic acids Guanine, Uracil, Adenine, and Cytosine (GCUA)\n\nUracil replaces Thyamine

One word contradicts your "facts". \n\nPlasmids.\n\nPlasmids are non-chromosomal loops of DNA found in bacteria.  They often contain antibacterial resistance genes, or give the ability to use different sugars.  These plasmids are commonly shared by bacteria.  This is a gain of genetic information.\n\nNow, it is true that we only have 4 types of nucleotides in DNA, and they make about 20 amino acids.  This is conserved in all life forms. But from this, a countless number of proteins can be made, and have a nearly infinite number of effects.  Your suggesting could be likened to saying that we can never invent a new word, since we only have 26 letters.  \n\nPlease provide a source for your claims, perhaps then we can understand how you arrived at such a conclusion.
