Adenovirus transcription is a two-phase event, early and late, occurring before and after viral DNA replication, respectively (Figure. (genemedi.com)
For most serotypes, adenovirus infection is mediated by the high-affinity binding of the fiber-knob region to a receptor of target cell, named as the coxsackie-Ad receptor (CAR), which mainly determines the viral tropism [44]. (genemedi.com)
Then the endosome acidifies, resulting in disassociation of capsid proteins and transportation of viral DNA into nucleus. (genemedi.com)
Life cycle of adenovirus is separated by DNA replication process into two distinct phases: the early and late, occurring before and after viral DNA replication, respectively. (genemedi.com)

Without integration into host genome, adenovirus genome remains in an episomal state, which guarantees the low risk of mutation (Fig. 8). (genemedi.com)
Moreover, the minimal genome requirements of AAV to replicate permit replacement of most of the genome with foreign DNA, resulting in a packaging capacity of up to 4.7 kb in standard AAV vectors, or about half of that in self-complementary AAV vectors (Fig. 1 ). (biomedcentral.com)

The mammalian genome comprises nuclear DNA (nDNA) derived from both parents and mitochondrial DNA (mtDNA) that is maternally inherited and encodes essential proteins required for oxidative phosphorylation. (regenerativemedicine.net)
Vectors3
On the other hand, Ad vectors also have a number of disadvantages, including their low transduction efficiency in cells lacking coxsackievirus-adenovirus receptor (CAR) and their induction of innate immune responses. (hindawi.com)
In order to overcome these disadvantages of the first-generation Ad vectors, next-generation Ad vectors, including fiber-mutant Ad vectors and helper-dependent Ad vectors, have been developed [ 6 - 8 ]. (hindawi.com)
