For a non-technical introduction to the topic, see Introduction to genetics.   The structure of part of a DNA double helix Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms and some viruses. The ... http://www.dnarna.org/dna/dna A gene is a locatable region of genomic sequence, corresponding to a unit of inheritance, which is associated with regulatory regions, transcribed regions and/or other functional sequence regions. The physical development and phenotype of organisms can be thought of as a product of genes interacting with each other and with ... http://www.dnarna.org/genetics/gene Ribonucleic acid or RNA is a nucleic acid made from a long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate. RNA is very similar to DNA, but differs in a few important structural details: in the cell RNA is usually single ... http://www.dnarna.org/rna/rna The origins of Madison's technology industry can be traced back much farther than 1982, but Fred Blattner felt pretty isolated when he opened DNASTAR, Inc. that year.

The function of the rRNA is to provide a mechanism for decoding mRNA into amino acids and to interact with the tRNAs during translation by providing peptidyl transferase activityShare This http://www.dnarna.org/rna/ribosomal-rna A non-coding RNA (ncRNA) is any RNA molecule that is not translated into a protein. A previously used synonym, particularly with bacteria, was small RNA (sRNA). However, some ncRNAs are very large (e.g. Xist). Less-frequently used synonyms are non-messenger RNA (nmRNA), small non-messenger RNA (snmRNA), or functional RNA (fRNA). The ... http://www.dnarna.org/rna/non-coding-rna DNA typing is performed by demonstrating differences in length of specific DNA sequences. This can be done by digestion of DNA with restriction enzyme(s), followed by Southern blot hybridization using a probe specific for the polymorphic site. Polymerase chain reaction (PCR) techniques are becoming widely applied to the same task, ... http://www.dnarna.org/dna-testing-services/techniques-for-dna-testing Structural proteins that bind DNA are well-understood examples of non-specific DNA-protein interactions. Within chromosomes, DNA is held in complexes with structural proteins. These proteins organize the DNA into a compact structure called chromatin. In eukaryotes this structure involves DNA binding to a complex of small basic proteins called histones, while ... http://www.dnarna.org/dna/dna-binding-proteins DNA polymerases are a family of enzymes critical for all forms of DNA replication. A DNA polymerase synthesizes a new strand of DNA by extending the 3' end of an existing nucleotide chain, adding new nucleotides matched to the template strand one at a time.
