For example the percentage of similarities between Gene and Cistron
when n-gram and synonym are applied is 77% and this percentage increased to 84% and 88% (Figure 4) when data type and role of the attribute, respectively are considered.
In fact, what the word gene names as the cause of a phenotypic effect is not a single cistron
at a single locus on a chromosome but rather the complex interaction of many cistrons
: "the use of single-locus models is just a conceptual convenience" (21).
Este trabalho teve por objetivo isolar e identificar isolados de Guignardia oriundos de citros, mangueira, goiabeira, eucaliptos, jabuticabeira e pitangueira, bem como caracterizar a diversidade genetica existente atraves da analise da sequencia de DNA do cistron
The peptide product of a 5' leader cistron
in the [[beta].sub.2] adrenergic receptor mRNA inhibits receptor synthesis.
(ITS) of the nuclear rDNA cistron
are important for understanding
The cryptomonad genome contains a short (4.9 kb) inverted repeat containing the rRNA cistrons
, 30 tRNA genes, 44 genes encoding proteins for photosynthesis, 44 ribosomal protein genes (26 large subunit and 18 small subunit), 5 genes for biosynthetic function, 19 genes involved in gene expression (including 3 hypothetical chloroplast reading frames or ycfs), 25 additional ycfs, and 9 open reading frames (ORFs) larger than 50 amino acids.
Most widely used has been the nuclear ribosomal RNA cistron
(rDNA), or portions thereof [ILLUSTRATION FOR FIGURE 1 OMITTED].
Regulatory elements in 5-UTRs may influence the translation of downstream cistrons
(Barrett et al.
In eukaryotic cells, rRNA cistrons
made up of 18S, 5.8S and 28S rRNA genes are transcribed by RNA polymerase I.
This pattern indicates that these chromosomal regions as poor cytotaxonomic markers, differing from other Atlantic fishes in which the identification of ribosomal cistrons
has proved to be efficient to distinguish apparently homogeneous karyotypes, as in Lutjanidae , Serranidae , and Gerreidae  or even population units [43, 44].
