exon

ex·on

(ek'son),
A portion of DNA that codes for a section of the mature messenger RNA obtained from that DNA, and is therefore expressed ("translated" into protein) at the ribosome.
[ex- + on]

exon

(ĕk′sŏn)
n.
A nucleotide sequence that is found in a gene, codes information for protein synthesis, and is transcribed to messenger RNA.

ex·on′ic adj.

exon

The segment of deoxyribonucleic acid (DNA) in a gene that codes for some part of the messenger ribonucleic acid (RNA). Any segment that is represented in the RNA product. Segments that do not code for RNA are called introns.

exon

or

extron

(‘ex'for expressed) or - the DNA segments of an INTERRUPTED split gene that are transcribed into RNA and then into the gene product. Exons occur along the length of the gene, and are separated by segments called INTRONS whose sequences are also transcribed into RNA. The intron RNA segments are then excised, leaving behind the exon RNA segments that join up to form a functional RNA molecule, a process called RNA SPLICING.

found an A/C mutation in the GnRHR exon 1 of Huanghuai goat and Boer goat and determined that the litter size of Huanghuai goats with the BB genotype is grearter than that of the AA genotype (Pa$?0.05) (Zhang YJ et al.
Within the exons of KCNE1, it is known that the last exon, where we found 653 C/T SNPs, participates in encoding protein Mink; thus, 653 C/T SNPs are the coding SNPs (cSNPs).
But erysipelas like erythema (ELE), arthritis, amyloidosis, and a family history of FMF were more common in patients with only exon 10 mutations (p<0.05) (Table 2).
The mutation results in the substitution of proline for alanine in exon 3 of PAX9 gene.
RsaI, on the other hand, receptor and none of the miss-located within the DBD is known to have 9 cleavage sites along the entire wild type hAR sequence; one of them is located in the third exon. Similar to BbvI, RasI showed a single abnormal pattern with lower prevalence (0%, 0%, 9% and 28.6%) in different groups, following the same order (Figure 4).

We surveyed 170 participating clinical laboratories from 20 countries regarding the number of clinical samples tested for EGFR mutations in a 12-month period (March 2013-March 2014); the number of cases with activating mutations in exons 18, 19, 20, and 21 (specifically L858R and L861Q); and the number of cases with the resistance mutations S768I and T790M in exon 20.
