The invention further relates to a prokaryotic expression cassette, a method of expressing a protein of interest in a prokaryotic cell, and to a prokaryotic cell comprising the prokaryotic expression cassette according to the invention.NIEUWKOOP, THIJS...
codon is 7 ± 2 nucleotides. As is the case for acloning vector, themultiple cloning sitecontains a series of unique restriction sitesthat facilitate the introduction of the heterologous gene. All organisms use thestop codonsTAA, TAG, andTGAbut TAA is the preferred sequence forE. coli. The ...
Related to Stop-codon:opal codon genetic code n. 1.The set of DNA and RNA sequences that determine the amino acid sequences used in the synthesis of an organism's proteins. It is the biochemical basis of heredity and nearly universal in all organisms. ...

Exonsusually include both the 5'- and 3'- untranslated regions of mRNA, which contain start and stop codons, in addition to any protein coding sequences. Do exons have stop codons? yes it is possible that start and stop codon may present within exonsbut if we see that very carefully then...
A string of nucleotides that code for a trait (characteristic) is called a gene, each gene is unique and requires a specific sequence of bases. There are four nitrogenous bases: adenine, thymine, guanine, and cytosine; the order of these bases on DNA strand is what determines the specific ...
54. Mutations that knock out A37-modifying enzymes have been shown to abolish UGA suppression fromSaccharomyces cerevisiaetRNACys(GCA) (Sc-tRNACys)22and strongly attenuate suppression (by 98.5% compared to the wild type) by Ec-tRNATrp(ref.21). We compared the sequence surrounding the anticodon ...
stop codonnoun语法 (biology), (genetics), (biochemistry) a sequence of three RNA nucleotides (A, C, G or U) that instruct the synthesis, or translation, of a protein to stop. The three-letter stop codon sequences have been given names: "UAG" isamber, "UGA" isopal, and "UAA" isoc...
Stop codon sequences are also enriched immediately after piRNA processing intermediates, reflecting their Zuc-dependent tail-to-head arrangement. Further analyses reveal that a Zuc in vivo cleavage preference at four sequences (UAA, UAG, UGA, UAC) promotes 5’ end stop codons. This observation is...
First, we introduced a heptameric premature stop codon sequence from a mutant HEXA variant (1278insTATC29) between RLuc and FLuc (Figure 4E). Using this reporter, we detected an increase of frameshifting in comparison to empty vector in our established in vitro T7 reticulocyte assay (Figure 4F...
