The sugar found in deoxyribonucleic acid, or DNA, is deoxyribose. It is a variant of the five-carbon sugar called ribose. DNA is an informational molecule found mainly in the nucleus of the cell.Know More
The primary structure of DNA contains a set of instructions or a code that allows it to replicate itself. It also guides the synthesis of proteins, which are mainly enzymes, a process that governs the metabolic activities of the cell, as stated by Harvard University.
DNA contains the genetic codes necessary to make ribonucleic acid, or RNA, found primarily in the material in the living cell. DNA comprises two intertwined strands within each molecule that form a double helix, identified by American biologist James D. Watson and British biologist Francis Crick in 1953.
The double helix comprises nucleotides, which are repeating units composed of a pentose sugar, a nitrogen-containing base and a triphosphate. Each chain of DNA has a chief support structure comprising phosphate-sugar-phosphate-sugar-phosphate.
Deoxyribose is a variant of ribose, which is a five-carbon sugar, and it is the origin of the name dioxyribonucleic acid. In deoxyribose, one of the hydroxyl, or OH, groups on the carbon is missing on the sugar, which is the way it differs from ribose.Learn more about Molecular Biology & DNA
Nucleotides contain either ribose, found in RNA, or deoxyribose, found in DNA. Deoxyribose is not synthesized in the cell, it is produced by action of the enyme ribonucleotided reductase on ribonucleotide diphoshates. Ribose is the product of the pentose phosphate pathway.Full Answer >
The full scientific name for DNA is deoxyribonucleic acid. Passed from adult organisms to their offspring, it contains the genetic instructions for the design of that organism.Full Answer >
DNA, which stands for deoxyribonucleic acid, is the hereditary material passed down from parents to progeny in almost all living organisms, including humans. DNA encodes sets of genes that govern every heritable attribute in living organisms.Full Answer >
During the extraction of deoxyribonucleic acid, or DNA, salt compounds such as sodium acetate and ammonium acetate are typically added to aid in the removal of DNA-associated proteins. Another type of salt compound called sodium chloride, or NaCl, helps in solidifying and making DNA visible. When mixed in an alcohol solution, the sodium component of NaCl provides a protective barrier around the negatively-charged DNA phosphate ends, enabling them to move closer to be extracted out of the solution.Full Answer >
