Unreliable PCR amplification of these loci is most likely in the non-passerine species, as they are more genetically distant from zebra finch and are therefore more likely to exhibit base mismatches in the primer binding regions.
Based on physical properties, CA repeats might be considered similar to random sequences in DNA (31), and should in theory exhibit base stacking and base-pair opening kinetics intermediate between the extremes of mononucleotide G or A runs.
In addition, for a smaller subset of snoRNAs that exhibit base complementarity to pre-rRNAs but do not guide endonucleolytic cleavages or nucleotide modifications, a chaperone-like function was also suggested but not experimentally validated (Vitali et al. 2003).
NAOMI PASACHOFF Williamstown, Mass., Dec. 18, 2003 The writer, a research associate at Williams College, is preparing an exhibit based on the college's Theodore Roosevelt collection.
On June 13, the museum will open an exhibit based on letters of the memories of people who have loved the space through the years.
The museum also encourages reading in its "Arthur's World" exhibit, based on the PBS series, and creativity in its messy art studio.
An exhibit based on the book is at the Queens Museum of Art in Flushing Meadows-Corona Park through March 14, with photographs, taped narratives, music and performances by several artists profiled in the book.
There will not be any such delays with "Night and Day," a collection of photographs by David Armstrong that were taken at the Mudd Club and other downtown Manhattan spots in the late 1970s and '80s that will coincide with an exhibit based on the book, opening at Half Gallery on June 26.
At least 350 km of major waterways and tributaries in the Swan-Avon Basin were found to exhibit base-flow acidity (pH < 4.5) along with low-level waters in a number of lakes.
In 1996, Universal Studios Islandss of Adventure in Orlando, Florida, commissioned the Brampton, Ontario, company to supply three robotically animated Triceratops for an outdoor exhibit based on the blockbuster movie Jurassic Park.
We also found that it was possible to predict, with 95% accuracy, which type of respiratory behaviour a soil would exhibit based on certain physical and chemical soil properties combined with the size and phenotypic structure of the microbial community.
