  2. DNA - Wikipedia

    en.wikipedia.org/wiki/DNA

    RNA strands are created using DNA strands as a template in a process called transcription, where DNA bases are exchanged for their corresponding bases except in the case of thymine (T), for which RNA substitutes uracil (U). [4] Under the genetic code, these RNA strands specify the sequence of amino acids within proteins in a process called ...

    en.wikipedia.org/wiki/Molecular_genetics

    The discovery of DNA as the blueprint for life and breakthroughs in molecular genetics research came from the combined works of many scientists. In 1869, chemist Johann Friedrich Miescher, who was researching the composition of white blood cells, discovered and isolated a new molecule that he named nuclein from the cell nucleus, which would ultimately be the first discovery of the molecule DNA ...

    en.wikipedia.org/wiki/Nuclear_DNA

    Nuclear DNA is a nucleic acid, a polymeric biomolecule or biopolymer, found in the nucleus of eukaryotic cells.Its structure is a double helix, with two strands wound around each other, a structure first described by Francis Crick and James D. Watson (1953) using data collected by Rosalind Franklin.

    en.wikipedia.org/wiki/DNA_sequencing

    DNA sequencing may be used along with DNA profiling methods for forensic identification [21] and paternity testing. DNA testing has evolved tremendously in the last few decades to ultimately link a DNA print to what is under investigation. The DNA patterns in fingerprint, saliva, hair follicles, etc. uniquely separate each living organism from ...

    When it comes to insects' DNA, humans have a bit less in common. For example, fruit flies share 61 percent of disease-causing genes with humans, which was important when NASA studied the bugs to ...

  7. Nucleic acid - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid

    The code is read by copying stretches of DNA into the related nucleic acid RNA in a process called transcription. Within cells, DNA is organized into long sequences called chromosomes. During cell division these chromosomes are duplicated in the process of DNA replication, providing each cell its own complete set of chromosomes.

  8. Blueprint - Wikipedia

    en.wikipedia.org/wiki/Blueprint

    A blueprint is a reproduction of a technical drawing or engineering drawing using a contact print process on light-sensitive sheets introduced by Sir John Herschel in 1842. [1] The process allowed rapid and accurate production of an unlimited number of copies.
