scattered antral spaces stage

The stage in oogenesis when antral spaces begin to form in the follicle cells. Mitochondria form centers for yolk concentration.

diplotene

The cell cycle phase which follows pachytene during prophase I of meiosis, during which the homologous chromosomes begin to separate and the synaptonemal complex dissolves.

neural fold elevation formation

The process in which the lateral borders of the neural plate begin to migrate upwards to form the neural folds, caused by the proliferation of the underlying mesoderm.

2-oxopropyl-CoM reductase (carboxylating) activity

Catalysis of the reaction: acetoacetate + coenzyme M + NADP+ = 2-oxopropyl-coenzyme M + CO2 + NADPH.

DNA ligase (ATP) activity

Catalysis of the reaction: ATP + deoxyribonucleotide(n) + deoxyribonucleotide(m) = AMP + diphosphate + deoxyribonucleotide(n+m).

DNA ligase (NAD+) activity

Catalysis of the reaction: NAD+ + deoxyribonucleotide(n) + deoxyribonucleotide(m) = AMP + nicotinamide nucleotide + deoxyribonucleotide(n+m).

obsolete thiol-driven fumarate reductase activity

OBSOLETE. Catalysis of the reaction: fumarate + coenzyme M + coenzyme B = succinate + coenzyme M + coenzyme B + heterodisulfide.

2-(R)-hydroxypropyl-CoM dehydrogenase activity

Catalysis of the reaction: 2-(R)-hydroxypropyl-coenzyme M + NAD+ = 2-oxopropyl-coenzyme M + H+ + NADH.

2-(S)-hydroxypropyl-CoM dehydrogenase activity

Catalysis of the reaction: 2-(S)-hydroxypropyl-coenzyme M + NAD+ = 2-oxopropyl-coenzyme M + H+ + NADH.

progression of morphogenetic furrow involved in compound eye morphogenesis

The morphogenetic furrow is a dorsoventral indentation which sweeps anteriorly across the eye disc. Ommatidia begin to form along the furrow, resulting in a graded series of ommatidial development across the anterior/posterior axis of the disc.
