inactivation

X-inactivation means that only one gets expressed in a particular cell, but this means individual photoreceptor cells can express either allele.

Also all fMRI experiments are characterised by a block design - periods of activation and inactivation - and the response is expected to correlate with these in some way.

Lyonization, or X-inactivation, is what happens if you have a cell with two X chromosomes.

Oxidative inactivation by oxygen is a big part of their loss of activity.

The process of generating these mice involves sophisticated techniques that enable scientists to manipulate the genome, leading to the inactivation of target genes.

This is as opposed to torties and calicos, which always by necessity have two X chromosomes (as the patchy pattern results from X-inactivation [1]).

See this recent paper [1] for an example of how water molecules affect potassium channel inactivation, a key process in cardiac electrophysiology and other areas.

At the inactivation ceremony a couple hours ago, the Secretary of the Navy announced (via video) that the next nuclear carrier after the Gerald R.

However, with X-chromosome inactivation, dominance takes place between cells.

Proper inactivation was controlled by the incubation of Vero E6 cells with the inactivated virus particles and subsequent screening for the presence of viral proteins (immunofluorescence) and viral RNA (reverse transcription [RT]-PCR targeting virus-specific transcripts).

For example, if the model were that simple, then men with Klinefelter's syndrome (who have two X and one Y chromosome in each cell, and whose cells also undergo an X-inactivation process) should experience a similar averaging for their IQ: Instead, Klinefelter's syndrome is held to be responsible for a drop in average IQ of nearly one standard deviation (compared to both men and women).

X-chromosome inactivation is actually consistent with X-linked "recessive" conditions, but it's a little tricky, and the wikipedia page doesn't really explain it.

Inactivation may not be effective and a virulent pathogen may survive and attenuated pathogens may pick up virulence factors and become fully functional from a different (related) patogen that happes to infect the patient at the same time.
