DNA ligase II: purification or excision repair of alternatively spliced form of DNA ligase III found in non-dividing cells. DNA ligase III: It is the only mammalian ligase that is found in mitochondria. It ligates DNA during the process of nucleotide excision repair and recombinant fragment. DN...

A common mechanism underlying SIPS is the activation of senescent cell anti-apoptotic pathways (SCAPs), which enable the survival of damaged cells by overriding pro-apoptotic signals [31]. The final senescent cell state, referred to as GX, represents a stable cell cycle arrest that can occur at...
[ 5 ]. in human for instance, it was estimated that despite the existence of a specific repair mechanism that restores g/c mismatch, the mutation rate from 5mc to t is 10 to 50-fold higher than other transitions [ 6 ]. it was estimated that within 20 years, 0.17% of all 5mc in...
Mechanism of cNLS-mediated protein transport Classical NLS on cargo proteins are recognized by the importin α subunit, which in turn is recognized by the importin β subunit. The resulting cNLS-cargo-importin α-importin β1 trimer is then imported into the nucleus through a series of steps ...
Given that cells rely on DNA for their very existence it is obvious that all cells must possess a high-fidelity mechanism to repair such damage and this is called double strand DNA break repair The DNA molecule has a phosphorus sugar backbone which is quite strong. The backbone of DNA runs...
In other organisms, such as algae, and some groups of bacteria, the parent cell divides multiple times and separates into multiple identical offspring. Using multiple fission, they grow and replicate cellular DNA multiple times, rapidly producing dozens or even hundreds of smaller cells called baeo...
CRISPR-Cas mediated DNA-interference typically relies on sequence-specific binding and nucleolytic degradation of foreign genetic material. Type IV-A CRISPR-Cas systems diverge from this general mechanism, using a nuclease-independent interference pathway to suppress gene expression for gene regulation and...
