Mansfield's prize-winning work expanded upon nuclear magnetic resonance (NMR), which is the selective absorption of very high-frequency radio waves by certain atomic nuclei subjected to a strong stationary magnetic field.
Figure 1D (see also Tables S1 and S2) shows a comparison of cotyledon and mature leaf nuclei subjected to DNA fluorescence in situ hybridization (DNA-FISH) using an A. thaliana-specific rRNA gene probe (green signals) in conjunction with immunolocalization of H3K9me2 (red signals).
Probe and target DNA were denatured simultaneously on a metal plate at 75°C for 2 min except for nuclei subjected to Hypo-MAA I fixation.
In our study, the total number of neurons in the lateral nucleus in subjects with autism was also less (by 17%) (4,609,751) than in the control group (5,544,098), but after control for five covariates, the difference was found to be not significant.
An atomic nucleus is subject to the same law.
For high-resolution microscopy, a fluorescent widefield microscope was used to produce 3D image of the nucleus and subjected to deconvolution (Supplemental Experimental Procedures).
Importantly, flies and worms lack an equivalent of mammalian choice: once the decision to initiate dosage compensation has been made, all X chromosomes in the nucleus are subjected to dosage compensation.
We expressed albumin in professional PC-I secretory cells (human fibroblasts) by microinjecting albumin cDNA in the nucleus and subjecting the cells to the synchronization protocol 1 ('Materials and methods').
As intron-containing mRNAs are frequently retained in the nucleus and/or subject to degradation, preferential intron retention in cancer cells could potentially suppress gene expression in the absence of compensatory transcriptional upregulation.
Multinucleated and ectopic neurons have also been reported in the cerebellum and vestibular nuclei of subjects with ALS/PDC (Shiraki and Yase 1975), an observation that suggests human exposure to MAM during early CNS development may have arrested the mitotic and migratory developmental responses of neurons.
Following irradiation, nuclei were subjected to RhoA or GEF activity assays.
