The progression of the mammary gland alveolus over time, from its formation to its mature state. The mammary gland alveolus is a sac-like structure that is found in the mature gland.

A reproductive behavior in which a parent cares for and rears offspring.

A parental behavior in which fertilized eggs are taken into the mouth and held until hatching.

The cell cycle process in which replicated homologous chromosomes are organized and then physically separated and apportioned to two sets during the first division of the meiotic cell cycle. Each replicated chromosome, composed of two sister chromatids, aligns at the cell equator, paired with its homologous partner; this pairing off, referred to as synapsis, permits genetic recombination. One homolog (both sister chromatids) of each morphologic type goes into each of the resulting chromosome sets.

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

The cell cycle process in which sister chromatids are organized and then physically separated and randomly apportioned to two sets during the second division of the meiotic cell cycle.

Catalysis of the sequential cleavage of nucleotides (such as mononucleotides or dinucleotides) from a free 5' terminus of a single-stranded DNA molecule.

Catalysis of the sequential cleavage of mononucleotides from a free 5' or 3' terminus of a single-stranded DNA molecule.

Catalysis of the sequential cleavage of mononucleotides from a free 5' terminus of a DNA molecule.

The activation, by acetate, of the chemical reactions and pathways resulting in the breakdown of acetate.

The activation of the chemical reactions and pathways resulting in the breakdown of acetate.

Catalysis of the hydrolysis of a single N-terminal amino acid residue from a tripeptide.

The chemical reactions and pathways involving acetoin, 3-hydroxy-2-butanone, often as part of a fermentation pathway or for use as a carbon source.

Catalysis of the reaction: phytoceramide + inositol phosphate = inositol phosphoceramide + diacylglycerol.

The directed movement of a chromosome to the nuclear envelope that contributes to homologous chromosome segregation and precedes synapsis.

Binding to a DNA triple helix. The formation of triple helical DNA has been evoked in several cellular processes including transcription, replication, and recombination.

The developmental growth process in which a branch of a mammary gland duct elongates.

The growth process in which a branch increases in length from its base to its tip.

Any process in which phytosterols are taken up from the contents of the intestine.

The multiplication or reproduction of mammary gland branch epithelial cells, resulting in the elongation of the branch. The mammary gland branch differs from the bud in that it is not the initial curved portion of the outgrowth.
