An inversion is a chromosome rearrangement in which a segment of a chromosome becomes inverted within its original position. An inversion occurs when a chromosome undergoes a two breaks within the chromosomal arm, and the segment between the two breaks inserts itself in the opposite direction in the same chromosome arm.
The classical example is the Drosophila w m4 (speak white-mottled-4) translocation.In this mutation, an inversion on the X chromosome placed the white gene next to pericentric heterochromatin, or a sequence of repeats that becomes heterochromatic. [3]
A hypercentric or pericentric lens is a lens system where the entrance pupil is located in front of the lens, in the space where an object could be located. In a certain region, objects that are further away from the lens produce larger images than objects that are closer to the lens.
The physical role of the centromere is to act as the site of assembly of the kinetochores – a highly complex multiprotein structure that is responsible for the actual events of chromosome segregation – i.e. binding microtubules and signaling to the cell cycle machinery when all chromosomes have adopted correct attachments to the spindle, so ...
This is called circle inversion or plane inversion. The inversion taking any point P (other than O ) to its image P ' also takes P ' back to P , so the result of applying the same inversion twice is the identity transformation which makes it a self-inversion (i.e. an involution).
A dicentric chromosome is an abnormal chromosome with two centromeres.It is formed through the fusion of two chromosome segments, each with a centromere, resulting in the loss of acentric fragments (lacking a centromere) and the formation of dicentric fragments. [1]
The YIFY name continued to generate traction to the point where in 2013 'YIFY' was the most searched term on Kickass Torrents, along with other related search terms such as 'yify 720p', 'yify 2013' and 'yify 1080p'. [7] This popularity was maintained through to 2015, where it was once again the most searched term on BitTorrent websites. [8]
IRC site channels will use modes such as +s (secret) +p (private) and +i (invite only) to avoid detection. Each release in The Scene consists of a folder containing the material (sometimes split into RAR pieces), plus an NFO and SFV file.
