Ordinarily, deficient expression of a DNA repair enzyme results in increased un-repaired DNA damage which, through replication errors (translesion synthesis), lead to mutations and cancer. However, PARP1 mediated MMEJ repair is highly inaccurate, so in this case, over-expression, rather than under-expression, apparently leads to cancer.
E. coli is one of the most widely used expression hosts, and DNA is normally introduced in a plasmid expression vector. The techniques for overexpression in E. coli are well developed and work by increasing the number of copies of the gene or increasing the binding strength of the promoter region so assisting transcription.

The protein manufacturing cost remains high and there is a growing demand to develop cost efficient and rapid protein purification methods. Understanding the different protein purification methods and optimizing the downstream processing is critical to minimize production costs while maintaining the quality of acceptable standards of homogeneity.

In eukaryotes, transcription is performed in the nucleus by three types of RNA polymerases, each of which needs a special DNA sequence called the promoter and a set of DNA-binding proteins—transcription factors—to initiate the process (see regulation of transcription below).
It is common for the degraded and fragile cell membrane to be lysed, releasing unwanted DNA and the desired proteins. The resulting DNA-protein extract is highly viscous and difficult to purify, in which case DNase is added to break it down. [11] The DNA is hydrolyzed but the proteins are unaffected and the extract can undergo further purification.
MutLα is shown to have weak ATPase activity and also possesses endonuclease activity that introduces nicks into the discontinuous strand of DNA. This facilitates 5' to 3' degradation of the mismatched DNA strand by EXO1. [13] The active site of MutLα is located on the PMS2 subunit. PMS1 and PMS2 compete for interaction with MLH1. [13]
(See Central dogma of molecular biology). mRNA structure, approximately to scale for a human mRNA, where the median length of 3′UTR is 700 nucleotides. In molecular genetics, the three prime untranslated region (3′-UTR) is the section of messenger RNA (mRNA) that immediately follows the translation termination codon.
