What are DNA helicases? What is the oldest DNA of any kind ever found? What does a mutation in the DNA do to the polypeptide? Fill in the blank. The enzyme that joins DNA complementary nucleotides together is ___. 1) What is the complementary strand of the DNA sequence GCAAT? a) ...
Silencing WRN can induce DNA double-strand breakage, activate DNA damage response, induce apoptosis and cell cycle arrest MSI tumors require WRN helicases but do not cause death of their own cells, suggesting that WRN may be a target for lethal synthesis [29]. The above studies indicate that...

the attenuation of the aging phenotype of HSCs [130]. Other studies defined replication stress as a driver of functional declines in HSCs during aging [131]. This was associated with decreased expression of mini-chromosomal maintenance helicase components and altered DNA replication fork dynamics [...
