DnaX ribosomal frameshifting element
Encyclopedia
The DnaX ribosomal frameshifting element is a RNA element
found in the mRNA of the dnaX
gene in E. coli. The dnaX gene has two encoded products tau and gamma which are produced in a 1:1 ratio. The gamma protein is synthesised due to programmed frameshifting
and is shorter than tau. The two products of the dnaX gene are DNA polymerase III
subunits.
Cis-regulatory element
A cis-regulatory element or cis-element is a region of DNA or RNA that regulates the expression of genes located on that same molecule of DNA . This term is constructed from the Latin word cis, which means "on the same side as". These cis-regulatory elements are often binding sites for one or...

DnaX
DnaX is the gene that codes for the τ and γ subunits of the DNA clamp loader of prokaryotes. The eukaryotic equivalent to the DNA clamp loader is Replication Factor C, which is encoded by RFC1, RFC2, RFC3, RFC4, and RFC5....

Reading frame
In biology, a reading frame is a way of breaking a sequence of nucleotides in DNA or RNA into three letter codons which can be translated in amino acids. There are 3 possible reading frames in an mRNA strand: each reading frame corresponding to starting at a different alignment...

DNA polymerase III holoenzyme
DNA polymerase III holoenzyme is the primary enzyme complex involved in prokaryotic DNA replication. It was discovered by Thomas Kornberg and Malcolm Gefter in 1970. The complex has high processivity DNA polymerase III holoenzyme is the primary enzyme complex involved in prokaryotic DNA...
