Yet the current quest among many multiracial artists to find fuller cultural expression goes beyond the "mulatto millennium" described by the author Danzy Senna in her cheeky 1998 essay about the wave of mixed-race-themed anthologies and memoirs, the rise of "ethnically ambiguous" models in fashion and magazines, and multiracial stars like Mariah Carey.
None of the ambiguous models is within the 10 most likely models for either rat so we do not discuss them further.
Joints are a key aspect of assembly models that are often ambiguous when model sharing takes place.
For example, the ambiguous intermediate model [ 5, 9] would explain the distribution of the non-canonical code in Ulvophyceae as follows: mutations in the anticodons of canonical glutamine tRNAs occurred once along the branch leading to the orders Trentepohliales, Dasycladales, Bryopsidales, Cladophorales and the genus Blastophysa.
The "ambiguous intermediate" model is a non-neutral model, which posits that codon reassignment occurs through an intermediate stage where a particular codon is ambiguously decoded by both the cognate tRNA and a tRNA that is mutated at locations other than at the anticodon, after which the mutant tRNA may take over decoding of the ambiguous codon if it is adaptive [ 9].
The evolved phage are a plausible, experimental example of the penultimate step in amino acid substitution under the ambiguous intermediate model.
Devising such ingenious, legally ambiguous business models takes practice.
Because of factors like insufficient detector areas, ambiguous interaction models and intrinsic fluctuations in the processes, the progress in this field has been very slow.
In addition, ambiguous gene models have been confirmed or revised by sequencing RT-PCR or RACE products.
The interpretation of PPI networks remains ambiguous and models to explain the universal structure of PPI networks have been proposed to be related to evolutionary principles such as duplication and mutation of a few ancestors [ 62] or to the potential of proteins to bind together because of their physical properties, such as binding affinity and folding [ 63].
