De dødes bibliotek The base damage by UVR is determined by the flexibility of the
DNA strand as well as nature and position of the base. CPDs are formed at higher quantity by cycloaddition reaction between two pyrimidine bases [] in single-stranded
DNA (ssDNA) and at the flexible ends of poly (dA)-(dT) tracts, but not at their rigid centre [50, 51].Bending
of DNA towards the minor groove reduces CPDs formation []. RecQ helicases (3'-5') belong to the Superfamily II group of helicases, which help to maintain stability of the genome and suppress inappropriate
recombination. Deficiencies and/or mutations in RecQ family helicases display aberrant
genetic recombination and/or
DNA replication, which leads to chromosomal instability and an overall decreased ability to proliferate. Mammalian
DNA topoisomerase (Topo) III belongs to the type IA
DNA Topo subfamily, whose members also include bacterial
DNA Topo I and Topo III, and yeast Topo III. S. cerevisiae Topo III may have a significant role in the unlinking of parental strands at the final stage
of DNA replication and/or in the dissociation of structures in mitotic cells that could lead to
recombination (summary by Li ... Mechanistic studies of DNA replication and genetic recombination azw download

enzymes in drug metabolism: Regulation of gene expression, enzyme activities, and impact of
genetic variation The vast range of maximum lifespan differences between species provides convincing evidence that longevity is genetically influenced. An elephant lives about 10−20 times longer than a mouse, yet both animals have roughly the same number of lifetime heartbeats — the elephant at 30 per minute and the mouse at 300 per minute. The
CRISPR-Cas system is a prokaryotic immune system that confers resistance to foreign
genetic elements such as those present within plasmids and phages that provides a form of acquired immunity.RNA harboring the spacer sequence helps Cas (
CRISPR-associated) proteins recognize and cut foreign pathogenic
DNA. Other RNA-guided Cas proteins cut foreign RNA.

DNMT1 composed of CXXC, tandem bromo-adjacent homology (BAH1/2), and methyltransferase domains bound to
DNA-containing unmethylated CpG sites. The CXXC specifically binds to unmethylated CpG dinucleotide and positions the CXXC-BAH1 linker between the
DNA and the active site of
DNMT1, preventing de novo methylation.

DNA è un lungo polimero costituito da unità ripetute di nucleotidi. La catena del
DNA è larga tra i 22 ed i 26 Ångström (da 2,2 a 2,6 nanometri) ed ogni unità nucleotidica è lunga 3,3 Ångstrom (0,33 nanometri). Sebbene ogni unità occupi uno spazio decisamente ridotto, la lunghezza dei polimeri di
DNA può essere sorprendentemente elevata, dal momento che ogni filamento può ...
