This
biology
image could be re-created
using
vector graphics
as an
SVG
file
. This has several advantages; see
Commons:Media for cleanup
for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with
{{
vector version available
|
new image name
}}
.
It is recommended to name the SVG file “Homologous Recombination.svg”—then the template Vector version available (or Vva ) does not need the new image name parameter. |
This biology image was
uploaded
in the
JPEG
format even though it
consists of non-photographic data
. This information could be stored more efficiently or accurately in the
PNG
or
SVG
format.
If possible, please upload a PNG or SVG version of this image without
compression artifacts
, derived from a non-JPEG source (or with existing artifacts
removed
). After doing so, please tag the JPEG version with
{{Superseded|NewImage.ext}}
and remove this tag. This tag should not be applied to photographs or scans. If this image is a diagram or other image suitable for
vectorisation
, please tag this image with
{{Convert to SVG}}
instead of
{{BadJPEG}}
. If not suitable for vectorisation, use

Summary
Description Homologous Recombination.jpg |
English:
A current model of meiotic recombination, initiated by a double-strand break or gap, followed by pairing with an homologous chromosome and strand invasion to initiate the recombinational repair process. Repair of the gap can lead to crossover (CO) or non-crossover (NCO) of the flanking regions. CO recombination is thought to occur by the Double Holliday Junction (DHJ) model, illustrated on the right, above. NCO recombinants are thought to occur primarily by the Synthesis Dependent Strand Annealing (SDSA) model, illustrated on the left, above. Most recombination events appear to be the SDSA type.
