Thus, one false start codon and three false stop codons occur as a total of 4(n - 2) x [2.sup.2(n-3)] values.
Start codon targeted (SCoT) polymorphism: a simple, novel DNA marker technique for generating gene-targeted markers in plants.
Type III viral IRESes require eIF4G, with HCV IRES being an exception [29]; HCV IRES interacts with eIF3 for recruitment of the 40S ribosomal subunit in close proximity to the start codon, circumventing the requirement for the 5' cap structure [1,19].

Association of the vitamin D receptor start codon polymorphism (FokI) with bone mineral density in postmenopausal Korean women.
Motif analysis of the 1.5-kb upstream region from the start codon probably corresponding to the promoter revealed a plant MYB-binding domain (AACCAAAC) at [approximately equal to] 1400 bp upstream and a G-box core sequence (CACGTG) at [approximately equal to] 1250 bp upstream of the start codon (Fig.
The only input required by the software was the location of the genome files and the start/stop locations for the alignment (in this case -70 to +50 where o is the first base in the start codon).
Primers (200ug/ml) were designed flanking the c1 gene and contained a ribosome binding site upstream of the c1 gene start codon (Figure 3).
The AUG mRNA codon codes for methionine and also acts as the start codon for all proteins.
(Nucleotide sequences are preceded by a minus sign when upstream from the start site.) The start site or start codon is the first codon of the first exon.
Such mRNAs begin with a 5'-AUG-3' start codon at or very near the 5' terminus of the message, and their lack of 5' untranslated leaders means that they also lack conventional Shine-Dalgarno homologies believed to exist in most prokaryotic messages.
Included in the transcript is a start codon at nucleotide position 36 and two overlapping canonical polyadenylation signals (Kozak, 1986) at nucleotide positions 1464 and 1468.
