During conjugation the donor cell provides a conjugative or mobilizable genetic element that is most often a plasmid or transposon.

During this process, new capsid subunits are synthesized according to the genetic material of the virus, using the protein biosynthesis mechanism of the cell.

During interphase ( the period of the cell cycle where the cell is not dividing ), two types of chromatin can be distinguished:

During this stage of the cell cycle this makes the individual chromosomes in many cells visible by optical microscope.

During the cell division cycle, a new centriole grows from the side of each of the existing " mother " centrioles.

During cell division these chromosomes are duplicated in the process of DNA replication, providing each cell its own complete set of chromosomes.

During fertilisation of the egg cell, a second, separate fertilization event gives rise to the endosperm, an extraembryonic structure that nourishes the embryo in a manner analogous to the mammalian placenta.

During these stages, two centrosomes, containing a pair of centrioles in animal cells, migrate to the two poles of the cell.
