NGC 4567/8, UGC 7776/7, PGC 42064/9, VV 219, [2] KPG 347, [3] Butterfly Galaxies, [4] Siamese Twin Galaxies, Siamese Twins Galaxies, Siamese Twins [5] [NB 1] NGC 4567 and NGC 4568 (nicknamed the Butterfly Galaxies [ 4 ] or Siamese Twins [ NB 1 ] [ 5 ] ) are a set of unbarred spiral galaxies about 60 million light-years away [ 1 ] in the ...
These types of false-positive variants are filtered out by the duplex sequencing method since mutations need to be accurately matched in both strands of DNA to be validated as true mutations. Duplex sequencing can theoretically detect mutations with frequencies as low as 10 −8 compared to the 10 −2 rate of standard NGS methods. [1] [2] [10]
The ISS year-long mission , also called the One-Year Mission, was an 11-month-long scientific research project aboard the International Space Station, which studied the health effects of long-term spaceflight. [2] The NASA Twins Study was conducted.
The double-helix model of DNA structure was first published in the journal Nature by James Watson and Francis Crick in 1953, [6] (X,Y,Z coordinates in 1954 [7]) based on the work of Rosalind Franklin and her student Raymond Gosling, who took the crucial X-ray diffraction image of DNA labeled as "Photo 51", [8] [9] and Maurice Wilkins, Alexander Stokes, and Herbert Wilson, [10] and base-pairing ...
The immortal DNA strand hypothesis was proposed in 1975 by John Cairns as a mechanism for adult stem cells to minimize mutations in their genomes. [1] This hypothesis proposes that instead of segregating their DNA during mitosis in a random manner, adult stem cells divide their DNA asymmetrically, and retain a distinct template set of DNA strands (parental strands) in each division.

Time for the Stars is a juvenile science fiction novel by American writer Robert A. Heinlein, published by Scribner's in 1956 as one of the Heinlein juveniles.The basic plot line is derived from a 1911 thought experiment in special relativity, commonly called the twin paradox, proposed by French physicist Paul Langevin.
Rosalind Franklin joined King's College London in January 1951 to work on the crystallography of DNA. By the end of that year, she established two important facts: one is that phosphate groups, which are the molecular backbone for the nucleotide chains, lie on the outside (it was a general consensus at the time that they were at the inside); and the other is that DNA exists in two forms, a ...
