The union of gametes of opposite sexes during the process of sexual reproduction to form a zygote. It involves the fusion of the gametic nuclei (karyogamy) and cytoplasm (plasmogamy).

The directed movement of water (H2O) into, out of, within or between cells.

Stimulates the hydrolysis and exchange of adenyl nucleotides by other proteins.

The central region of a chromosome that includes the centromere and associated proteins.

The directed movement of dicarboxylic acids into, out of, within or between cells.

gamma DNA-directed DNA polymerase activity

Catalysis of the reaction: deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1). The DNA-directed DNA polymerase responsible for the replication of mitochondrial DNA.

A multisubunit complex that is located at the pericentric region of DNA and provides an attachment point for the spindle microtubules.

The directed movement of a neurotransmitter into, out of, within or between cells. Neurotransmitters are any chemical substance that is capable of transmitting (or inhibiting the transmission of) a nerve impulse from a neuron to another cell.

Catalysis of the synthesis of short RNA primers for the Okazaki fragments on both DNA template strands at the replication fork. A DNA-directed RNA polymerase that forms a complex with alpha DNA polymerase.

A multisubunit complex that is located at the pericentric region of a condensed chromosome and provides an attachment point for the spindle microtubules.

The central region of a condensed chromosome that includes the centromere and associated proteins, including the kinetochore.

Transport of substances into, out of or within a mitochondrion.

Catalysis of the reaction: nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1), while utilizing a DNA template: i.e. the catalysis of DNA-template-directed extension of the 3'-end of an RNA strand by one nucleotide at a time. Can initiate a chain 'de novo'.

Catalysis of the reaction: sugar(out) + cation(out) = sugar(in) + cation(in).

The series of events by which an external stimulus is received and converted into a molecular signal.
