1 Cytarabine, commonly known as TarabineÂ®, CytarabineÂ®, or Cytosar-UÂ®, is a drug used to treat certain cancers, most notably leukemia found in dogs and cats. 2  Chemically, it is a pyrimidine analog that functions inside cells as an antimetabolite.rand Names and Other Names of Cytarabine. 1  This drug is registered for use in humans only. 2  Human formulations: TarabineÂ® (Adria), CytarabineÂ® (Faulding), Cytosar-UÂ® (Gensia Sicor), and generic cytarabine.
According to Biologists, synapsis is only known to occur in  prophase 1 stage in meiosis because it is responsible for paring  homologous chromosomes. This event does not oc â¦ cur in mitosis. Suzanne (Zanbabe) Benner. 1,477,969 Contributions.
Meiosis II Chromosomal replication does not occur between meiosis I and meiosis II; meiosis I proceeds directly to meiosis II without going through interphase. The second part of the meiosis, meiosis II, resembles mitosis more than meiosis I. Chromosomal numbers, which have already been reduced to haploid (n) by the end of meiosis I, remain unchanged after this division. In meiosis II, the phases are, again, analogous to mitosis: prophase II, metaphase II, anaphase II, and telophase II (see figure below). As shown in the figure below, meiosis II begins with two haploid (n = 2) cells and ends with four haploid (n = 2) cells.
