The hierarchical steps resulting in the progressive subdivision of the anterior/posterior axis of the embryo.

Interacting selectively with oligo(A) and oligo(T) tracts of DNA (AT DNA).

Subdivision of the embryo along the anterior/posterior axis into anterior, posterior and terminal regions.

zygotic determination of dorsal/ventral axis

The specification of the dorsal/ventral axis of the embryo, through the products of genes expressed in the zygote.

Interacting selectively with chromatin, the network of fibers of DNA and protein that make up the chromosomes of the eukaryotic nucleus during interphase.

zygotic determination of anterior/posterior axis, embryo

The specification of the anterior/posterior axis of the embryo by products of genes expressed in the zygote; exemplified in insects by the gap genes, pair rule genes and segment polarity gene cascade.

Interacting selectively with damaged DNA.

Specification of the anterior (head and thoracic segments) of the embryo by the gap genes; exemplified in insects by the actions of hunchback gene product.

Interacting selectively with the DNA replication origin, a unique DNA sequence of a replicon at which DNA replication is initiated and proceeds bidirectionally or unidirectionally.

Activity that loads a ring-like DNA polymerase processivity factor, or sliding clamp, on to DNA, coupled to the hydrolysis of ATP.

specification of segmental identity, head

The specification of the characteristic structures of the head segments following establishment of segment boundaries. Identity is considered to be the aggregate of characteristics by which a structure is recognized.

specification of segmental identity, labial segment

The specification of the characteristic structures of the labial segment following establishment of segment boundaries. Identity is considered to be the aggregate of characteristics by which a structure is recognized.

specification of segmental identity, maxillary segment

The specification of the characteristic structures of the maxillary segment following establishment of segment boundaries. Identity is considered to be the aggregate of characteristics by which a structure is recognized.
