American Heritage® Dictionary of the English Language, Fourth Edition
- n. The stage of mitosis and meiosis, following prophase and preceding anaphase, during which the chromosomes are aligned along the metaphase plate.
Century Dictionary and Cyclopedia
- n. In cytology, the second or middle stage of karyokinetic cell-division, or mitosis, in which the chromosomes are collected to form the equatorial plate of the spindle and undergo longitudinal fission. Compare anaphase and telophase.
Wiktionary
- n. the stage of mitosis and meiosis, that follows prophase and comes before anaphase, during which condensed chromosomes become aligned before being separated

Examples
“Standard cytogenetic analysis including preparation of karyotypes, metaphase and interphase based fluorescence in situ hybridization (FISH), high resolution single nucleotide polymorphism oligonucleotide based array (SNP array) analysis and mutation analysis of the INI1/SMARCB1 gene are available.”
“Okay - it's out there, but the third cake the second set of bat cupcakes looks like chromosomes in metaphase to me.”
“It predicts that spindle microtubules in animal cells begin to oscillate at the beginning of prometaphase, and that those oscillations rapidly accelerate until metaphase,.”
“He neglects to mention that metaphase I oocyte chromosome alignment is mechanistically different from mitosis the chromosomes are physically tethered to each other, and that metaphase II, which is mechanistically similar to mitosis, does have abnormalities.”
“He reports that while Xkid deficient frog cells have PEF defects, frog oocytes have normal metaphase I.”
“The chromokinesin Kid is required for maintenance of proper metaphase spindle size.”
“It the hypothesis predicts that spindle microtubules in animal cells begin to oscillate at the beginning of prometaphase, and that those oscillations rapidly accelerate until metaphase, at which point they decelerate or cease.”
“By metaphase the oscillations may be of such high frequency that they would be difficult to detect, but the lower frequency oscillations early in prometaphase should be detectable by immunofluorescence microscopy and high-speed camera technology.”
“However, injected cells lack chromosome oscillations, and chromosome orientation is atypical because chromosome arms extend toward spindle poles during both congression and metaphase.”
