Correction of replication errors by DNA polymerase using a 3'-5' exonuclease activity.

The disruption of the bond between the sugar in the backbone and the A or G base, causing the base to be removed and leaving a depurinated sugar.

The process in which anatomical structures of the mammary gland cord are generated and organized. Mammary gland cords form when the mammary gland bud invades the mammary fat.

The process in which the anatomical structures of a tube are generated and organized from an epithelium. Epithelial tubes transport gases, liquids and cells from one site to another and form the basic structure of many organs and tissues, with tube shape and organization varying from the single-celled excretory organ in Caenorhabditis elegans to the branching trees of the mammalian kidney and insect tracheal system.

The process whose specific outcome is the progression of a neuromast hair cell over time, from its formation to the mature structure. A neuromast hair cell is a hair cell that acts as a sensory receptor of the neuromast; it is morphologically polarized as a result of the relative position of the single kinocilium and the clusters of stereocilia on its apical surface. Cell development does not include the steps involved in committing a cell to a specific fate.

The process in which a relatively unspecialized epithelial cell becomes a more specialized epithelial cell of the mammary gland cord. Epithelial cells of the mammary cord give it its funnel-like shape and some are cornified.

The process in which an oligopeptide is transported across a membrane. Oligopeptides are molecules that contain a small number (2 to 20) of amino-acid residues connected by peptide linkages.

The directed movement of oligopeptides into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Oligopeptides are molecules that contain a small number (2 to 20) of amino-acid residues connected by peptide linkages.

The multiplication or reproduction of mammary gland bud epithelial cells, resulting in the elongation of the bud.

Enables the transfer of a peptide from one side of a membrane to the other.

Any process that modulates the frequency, rate or extent of mammary gland bud epithelial cell proliferation that results in the elongation of the bud.

Any process that modulates the frequency, rate or extent of mammary gland epithelial cell proliferation.

Any process that modulates the rate, frequency, or extent of branching of the mammary gland cord as a result of a signal being created by a mammary fat precursor cell and its subsequent reception and interpretation by a mammary cord epithelial cell.

The change in form (cell shape and size) that occurs when an anterior lateral line neuromast hair cell progresses from its initial formation to its mature state. A neuromast hair cell is a hair cell that acts as a sensory receptor of the neuromast; it is morphologically polarized as a result of the relative position of the single kinocilium and the clusters of stereocilia on its apical surface.

Any process that modulates the rate, frequency, or extent of mammary gland cord elongation as a result of a signal being created by a mesenchymal cell that is a precursor to the mammary fat and its subsequent reception and interpretation by an mammary cord epithelial cell.

The process whose specific outcome is the progression of an anterior lateral line neuromast hair cell over time, from its formation to the mature structure. A neuromast hair cell is a hair cell that acts as a sensory receptor of the neuromast; it is morphologically polarized as a result of the relative position of the single kinocilium and the clusters of stereocilia on its apical surface. Cell development does not include the steps involved in committing a cell to a specific fate.

The process in which the mammary gland sprout grows along its axis.

The process whose specific outcome is the progression of a posterior lateral line neuromast hair cell over time, from its formation to the mature structure. A neuromast hair cell is a hair cell that acts as a sensory receptor of the neuromast; it is morphologically polarized as a result of the relative position of the single kinocilium and the clusters of stereocilia on its apical surface. Cell development does not include the steps involved in committing a cell to a specific fate.

The process in which the branching structure of the mammary gland cord is generated and organized. The mammary gland cord is a solid epithelial structure that will hollow out, forming the mammary duct.

The process in which the nipple is generated and organized.
