Accordingly, the aa under selection remain protected from loss because selection increases their frequency as they become rare, but consequent fluctuations in protein frequencies increase drift and fixation of partially linked silent substitutions.
For those that contained multiple mutations, the individual mutations could all contribute in an additive manner or some of these mutations could be silent or partially deleterious.
Longitudinal research would be particularly welcome to explore the precise role of an inhibited temperament and social anxiety in the development of young children who remain partially or even fully silent in specific social situations.
"Silent Sam" is now partially covered to hide the graffiti.
The VSG pseudogenes could be copies of silent VSG pseudogenes, or partially assembled mosaics, or genes that have degenerated in situ through lack of requirement for expression.
The PRC2 Polycomb group complex is partially responsible for keeping the maternal allele silent in the female gametophyte and in the seed after fertilization [ 19- 21].
In slice preparations, PCs of BK−/− mice have a dramatic decrease in spontaneous firing relative to PCs from wild-type (WT) mice, partially explained by an increase in time in silent mode.
"Our findings underscore the importance of correcting anemia, at least partially, and may thus lay the groundwork for primary prevention of silent stroke," said principal investigator Michael DeBaun, of Vanderbilt University, the lead author on the current report.
In addition, J. Stuart Blackton directed a 1923 silent film of the same title that was based partially on the song's lyrics.
However these results could be partially explained with the low single-center study population or with silent neurological damage among asymptomatic patients.
