n.
A codon, AUG in eukaryotes and either GUG or UUG in bacteria, that signals the initiation of translation and the first amino acid in a polypeptide chain. Also called chain initiation codon.

Direct sequencing of all 11 exons of PRKAR1A of this patient identified a 88 A to G mutation, which changes the initiator ATG to a GTG codon, abolishes the translational start codon but does not introduce a premature stop codon [Figure 1]e.
We now identified m1A which decorates thousands of genes mainly in the start codon vicinity, upstream to the first splice site.
The objective of this study was to use two molecular marker systems, start codon targeted (SCoT) and inter-simple sequence repeat (ISSR), to assess the genetic relationship and diversity of 75 sugarcane parental clones from Chinese sugarcane breeding program.
The trigger RNA finds the complementary single-stranded toehold sequence and opens up the ribosome binding site (RBS) [3] and start codon within its hairpin structure.
Hence, the restriction sites for NdeI and EcoRI were introduced before the start codon and after the stop codon respectively in the confirmed gene sequence.
Sequencing analysis of the ompk35 and ompk36 genes revealed the presence of the insertion sequence IS1 between the promoter region and the start codon of the ompK35 gene, and the presence of the IS908 disrupting the ompK36 gene.
There are 64 codons; 61 correspond to the 20 amino acids of which 1 (AUG) is a start codon.
Tusavims has a potential upstream start codon MSS in a weaker Kozak consensus sequence than MAQ (Figure, panel A), which we selected as the start codon.
The codon AUG codes for the initiation of the translation process and is therefore also known as start codon.
All these polymorphisms are numbered relative to the adenine of the translation start codon.
Textbooks of my college era discussed genes in terms of proposed models of cistrons, recons, and mutons; were missing the start codon in charts of the genetic code; and listed "nonsense" for what we know as stop codons (Keeton, 1967).
