The cell cycle process in which the sister chromatids of a replicated chromosome become tethered to each other.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an electromagnetic radiation stimulus. Electromagnetic radiation is a propagating wave in space with electric and magnetic components. These components oscillate at right angles to each other and to the direction of propagation.

Any process that stops, prevents, or reduces the frequency, rate or extent of initiation of DNA-dependent DNA replication.

Any process that stops, prevents, or reduces the frequency, rate or extent of initiation of DNA-dependent DNA replication.

The formation of a protein homotetramer, a macromolecular structure consisting of four noncovalently associated identical subunits.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the nucleoid. The nucleoid is the region of a bacterial cell, virion, mitochondrion or chloroplast to which the DNA is confined.

Any process that stops, prevents, or reduces the frequency, rate or extent of DNA replication.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

A protein-DNA complex that contains an oligomer of SeqA bound to GATC sites in methylated or newly-synthesized, hemi-methylated double-stranded DNA, with preference for the latter. Binding of SeqA to hemimethylated DNA sequesters oriC, prevents re-methylation of DNA by Dam and in turn stops premature re-initiation of replication during one replication cycle.
