Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Munguva yaaiva kuMissouri, McClintock akawedzera kutsvakurudza kwake pamusoro pezvinokonzerwa nemwaranzi yeX-ray pamasero ezviyo. McClintock akacherechedza kuputsika nokubatanidzwa kwema chromosomes mumasero emupunga airatidzwa mwaranzi. Akakwanisawo kuratidza kuti, mune zvimwe zvinomera, kuparara kwemakromosome kwaiitika mumasero endosperm. Mukati mokupindana, akacherechedza kuti migumo yema chromatids yakaputsika yakabatanidzwazve pashure pokunge makromosome apindazve. Muchikamu chinonzi anaphase chemitosis, makromosome akaputsika akaumba bhiriji re chromatid, iro rakaputsika apo makromatid akafamba akananga kumativi maviri emasero. Migumo yakaputsika yakabatanidzwazve muchikamu chepakati chechikamu chinotevera, uye kutenderera kwacho kwakadzokororwa, kuchikonzera kushanduka kukuru, uko aigona kuona sekusiyana-siyana mu endosperm. Uku kuputsika kwedenderedzwa rebhiriji raiva chinhu chinokosha chakawanikwa muzvinyorwa zvecytogenetics nokuda kwezvikonzero zvinoverengeka. Chokutanga, chakaratidza kuti kubatanidzwazve kwemachromosomes kwakanga kusiri chiitiko chisina kurongwa, uye chechipiri, chakaratidza kwaibva kushanduka-shanduka kukuru. Nokuda kwechikonzero ichi, inoramba iri nzvimbo inofarira mukutsvakurudza kwekenza nhasi. Kunyange zvazvo kutsvakurudza kwake kwaifambira mberi muMissouri, McClintock akanga asina kugutsikana nechinzvimbo chake paYunivhesiti. Akayeuka kuti akanga asingabvumirwi kupinda misangano yevadzidzisi, uye akanga asingaziviswi nezvemabasa akanga aripo pane dzimwe nzvimbo. Muna 1940, akanyorera Charles Burnham, kuti: "Ndasarudza kuti ndinofanira kutsvaka rimwe basa. Sezvandinogona kunzwisisa, hapana chimwe chinhu kwandiri pano. Ndiri purofesa webetsero ane $3.000 uye ndinonzwa ndine chokwadi chokuti ndiwo muganhu wangu". Pakutanga, nzvimbo yaMcClintock yakagadzirwa zvikurukuru nokuda kwake naStadler, uye ingave yakabva pakuvapo kwake kuyunivhesiti. McClintock akatenda kuti aisazowana chigaro kuMissouri, kunyange zvazvo maererano nedzimwe nhoroondo, aiziva kuti aizopiwa kukwidziridzwa kubva kuMissouri muchirimo cha1942. Ufakazi hwazvino uno hunoratidza kuti McClintock sezvingabvira zvikuru akasarudza kusiya Missouri nemhaka yokuti akanga arasikirwa nechivimbo mumushandirwi wake uye muhurumende yeYunivhesiti, pashure pokuwana kuti basa rake raiz...  Mubvunzo: Akapiwa nzvimbo pachikoro chipi?
