WebAsam deoksiribonukleat, lebih dikenal dengan singkatan DNA ( bahasa Inggris: deoxyribonucleic acid ), adalah salah satu jenis asam nukleat yang memiliki kemampuan pewarisan sifat. Keberadaan asam deoksiribonukleat ditemukan di dalam nukleoprotein yang membentuk inti sel. James Dewey Watson dan Francis Crick merupakan ilmuwan … DNA is a long polymer made from repeating units called nucleotides. The structure of DNA is dynamic along its length, being capable of coiling into tight loops and other shapes. In all species it is composed of two helical chains, bound to each other by hydrogen bonds. Both chains are coiled around the same axis, … See more Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth … See more DNA usually occurs as linear chromosomes in eukaryotes, and circular chromosomes in prokaryotes. The set of chromosomes in a cell makes up its genome; the human genome has approximately 3 billion base pairs of DNA arranged into 46 … See more A DNA helix usually does not interact with other segments of DNA, and in human cells, the different chromosomes even occupy separate areas in the nucleus called " See more Genetic engineering Methods have been developed to purify DNA from organisms, such as phenol-chloroform extraction, … See more Base modifications and DNA packaging The expression of genes is influenced by how the DNA is packaged in chromosomes, in a … See more All the functions of DNA depend on interactions with proteins. These protein interactions can be non-specific, or the protein can bind specifically to a single DNA sequence. Enzymes can also bind to DNA and of these, the polymerases that copy the DNA base … See more DNA contains the genetic information that allows all forms of life to function, grow and reproduce.

WebJul 8, 2009 · National Center for Biotechnology Information WebThe structure of DNA is very complex and it is synthesized in the nucleus with the help of DNA polymerase. Any defect in the process of replication of DNA can lead to mutation and it may result in a genetic deformity. The three units of DNA are: Nitrogenous bases: Adenosine, thymine, guanine, and cytosine are the four nitrogenous bases. WebJun 16, 2014 · Explanation: DNA are the letters of deoxyribonucleic acid. All life on earth uses this nucleic acid as the genetic code. A nucleic acid is a polynucleotide. A polynucleotide consists of three basic units: a phosphate group, a 5 carbon sugar (pentose), and a nitrogenous base. The five carbon sugar is deoxyribose. make main screen windows 10
