We then placed the fish in a 20 × 12.5 × 45 cm chamber filled with freshwater and positioned the fish on a plastic platform with lateral supports.
Here we aim to reveal the origin, distribution and mechanisms leading to the linked organisation of rDNA in the Asteraceae by analysing unit structure (PCR, Southern blot, sequencing), gene copy number (quantitative PCR) and chromosomal position (FISH) of 5S and 35S rRNA genes in ~200 species representing the family diversity and other closely related groups.
Check that the fishing line loop is strong enough to prevent the display from falling into the fully open position (fishing line comes in a variety of strengths, use a relatively strong line which will not stretch under the load).
The anesthetized animal was gently placed in a water-soaked gauze-wrapped hemostat with the abdomen facing up and the head of the fish positioned at the hinge of the hemostat (the pectoral fins were used as a landmark on the abdomen).
The traditional position — the fish's position — was: Don't save us from ourselves.
Whereas conventional aquaculture often falls down on sustainability by the consumption of fish food from wild caught fish, the black soldier flies here eat until they pupate, then self-harvest with the aid of a cleverly positioned ramp and become fish food.
Up to 100 photo-sensitive cells form a retina, which is positioned so any bird, fish, or other predator up to 2 meters away registers as an image there.
Heard, for instance, used FISH probes positioned on either side of DXZ4 to visually demonstrate that chromosome folding differs on the active and inactive X chromosomes in mice, thus validating her Hi-C findings.
The anesthetized fish are positioned dorsally in a v-shaped agarose injectionmold.
Although within the central heterochromatin a limited set of RH sequence blocks could still be aligned to DM superscaffold 33 and positioned by a single FISH anchor, a credible ordering of the remaining large volume of RH and DM sequence blocks in this region was not possible.
