termination codon One of three three-base sequences that initiate termination of the protein synthesis process. See stop codon.
Termination codon see stop codon
Transcription The process of copying DNA into RNA mediated by the enzyme RNA polymerase.
Transfection Transfer of DNA (usually of a gene) into a cultured cell where it can be expressed.
Termination codon. Any of three mRNA sequences (UGA, UAG, UAA) that do not code for an amino acid and thus signal the end of protein synthesis. Also known as stop codon. (See Codon.) ...
TERMINATION CODON - See STOP CODON.
TERMINATOR - A sequence downstream from the 3' end of an open reading frame that serves to halt transcription by the RNA polymerase.
Premature Termination Codons (PTCs); that is, the introduction of a STOP codon before the normal end of the message. Translation of these mRNAs produces a truncated protein that is probably ineffective and may be harmful.
binds to the termination codons and allows protein synthesis to continue.

Since approximately 50% of the cDNA clones isolated by either method was found to retain an in-frame termination codon upstream of the first ATG codon, it was speculated that more than half of the clones analyzed harbored complete ORF.
The genetic code consists of 61 amino-acid coding codons and three termination codons, which stop the process of translation.
The sequence of DNA or RNA located between the start-code sequence (initiation codon) and the stop-code sequence (termination codon).
Operon
A set of genes transcribed under the control of an operator gene.
Stop codons are also called termination codons and they signal release of the nascent polypeptide from the ribosome due to binding of release factors in the absence of cognate tRNAs with anticodons complementary to these stop signals.[2] ...
