(n.) A fault in speaking or in composition, which consists in too frequent use of the letter l, or in doubling it erroneously.
(n.) A defect in pronunciation of the letter l when doubled, which consists in giving it a sound as if followed by y, similar to that of the letters lli in billion.
(n.) The use of the sound of l for that of r in pronunciation; lallation; as, Amelican for American.
Example Sentences:
(1) The lambdagt clones containing fragments of the Drosophila melanogaster genome were prepared and characterized by hybridization of their DNA with (I) lambdagt-cRNA; (2) lambdaC-cRNA; (3) Dm-cRNA; (4) the mRNA of D.melanogaster culture cells and (5) the stable cytoplasmic poly (A) RNA from the same source.
(2) Two lines of evidence suggest that this failure probably results from interference with expression of the lambdacI gene, which codes for repressor, or with repressor action:-(i) when a lon(-) mutant was infected with a lambdacII, cIII, or c Y mutant, there was an additive effect between the lon(-) mutation and the lambdac mutations upon reduction of lysogenization frequency; and (ii) lon(-) mutants permitted the growth of the lambdacro(-) mutant under conditions in which the repressor was active.
(3) The antigenic composition of the bacteriophages lambdaC1857 and lambdagt-lambdaC was investigated by modified immunoelectrophoresis in a 1,2% agarose gel involving 1% Triton X-100 and 0,25% sodium desoxycholate.
(4) Recombinant phages have been constructed in vitro by joining the smaller fragment of ribosomal DNA and the outer arms of DNA from the vector lambdagtWES-lambdaC.
(5) Approximately 6% of Escherichia coli K12 (lambda wild-type) cells whose prophage was induced by treatment with N-methyl-N-nitrosourea initiated plaques on E. coli K12S which contained wholly or mostly clear plaque-forming mutants (lambdac).
(6) The phages lambdaC1857 and lambdagt-lambdaC were shown to have identical antigenic compositions and to comprise three basic antigens, such as a1, a2, a3.
Rhotacism
Definition:
(n.) An oversounding, or a misuse, of the letter r; specifically (Phylol.), the tendency, exhibited in the Indo-European languages, to change s to r, as wese to were.
Example Sentences:
