In most regions, the fibers are much less densely packed than in the mitotic chromosome. This material is called euchromatin. It has a relatively dispersed appearance in the nucleus and occupies most of the nuclear region.

Gibberellin appears to promote flowering in Arabidopsis by activating expression of the LEAFY gene.

The activation of LFY by gibberellin is mediated by the

transcription factor GA-MYB

Dispersal is the movement of individuals from one area to another.

Dispersal involves individuals leaving their habitat of origin—where a seed was made or where a squirrel was born—and typically not returning.

When DNA is extensively damaged (such as by UV light. RecA protein binds to this damaged, single-stranded DNA, activating the protein's coprotease activity. While bound to DNA, the RecA protein facilitates cleavage and inactivation of the Lex and Lambda repressor.
