An origin of replication refers to the specific sites where DNA replication initiates. Techniques such as small nascent strand purification are used to map these origins by isolating small-sized nascent DNA fra

of RNA dependent evolutionary processes that lead to the emergence of replication, genes, recombination, and repair. The top to bottom journey into the past starts with the concept of Popper’s deductive cycle. It leads us through established knowledge accompanied by the conserved mechanism of ...
DNA replication starts with the orderly assembly of the pre-replicative complex (pre-RC) at the origins of replication initiated by the binding of multiprotein origin recognition complex (ORC). From: Biochemical Pharmacology, 2021 About this pageSet alert ...
Metazoan cells only utilize a small subset of the potential DNA replication origins to duplicate the whole genome in each cell cycle. Origin choice is linked to cell growth, differentiation, and replication stress. Although various genetic and epigenetic
The formation and consequences of polyploidization in animals with clonal reproduction remain largely unknown. Clade I root-knot nematodes (RKNs), characterized by parthenogenesis and allopolyploidy, show a widespread geographical distribution and extens
evolutionary evidence for the zoonotic origin of viruses such as heni- pavirus, HanV, AreV, SARS-CoV, and MERS-CoV [10, 32–36, 85, 86], the presence of numerous vertebrate- irrelevant viral sequences in oral and rectal virome data complicated the definition of the host-virus relation-...
Carcinogenesis is widely thought to originate from somatic mutations and an inhibition of growth suppressors, followed by cell proliferation, tissue invasion, and risk of metastasis. Fewer than 10% of all cancers are hereditary; the ratio in gastric (1%)
