Progression through the phases of the mitotic cell cycle, the most common eukaryotic cell cycle, which canonically comprises four successive phases called G1, S, G2, and M and includes replication of the genome and the subsequent segregation of chromosomes into daughter cells. In some variant cell cycles nuclear replication or nuclear division may not be followed by cell division, or G1 and G2 phases may be absent.

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

A series of molecular signals within the cell that are mediated by a member of the Ras superfamily of proteins switching to a GTP-bound active state.

The projection of branches of an open tracheal system towards their target tissues. An example of this is found in Drosophila melanogaster.

The process in which the anatomical structures of the imaginal disc-derived wing are generated and organized. The wing is an appendage modified for flying.

A series of molecular signals initiated by the binding of an extracellular ligand to torso (a receptor tyrosine kinase) on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription.

The specification of the anterior/posterior axis of the embryo by the products of genes expressed maternally and genes expressed in the zygote.

The cell cycle process in which genetic material, in the form of chromosomes, is organized and then physically separated and apportioned to two or more sets during the meiotic cell cycle in a female.

Any process that activates or increases the frequency, rate or extent of R7 cell differentiation.

Any process that stops, prevents, or reduces the frequency, rate or extent of Ras protein signal transduction.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
