摘要： 我们创建了一个新的染色体模型:YR-黏和染色体模型,30nm螺线管通过JW-梯(或YR-梯)、染色线经螺旋化形成染色体[1].通过包装比、长度的推算、染色体结构的推算、以及碱基对的推算都与实验观测值吻合,确认了YR-黏和模型的可信度.YR-染色体模型能自然、合理地解释所有遗传现象,如交换、着丝粒、全身着丝粒或弥散型着丝粒染色体、同源染色体联会及联会复合体的中央区、多线染色体与膨突、灯刷染色体、染色体分带、姊妹染色体由前期到中期不分开、花粉管会导入外源遗传物质、高等生命是怎样从原始生物进化而来的等等。
Abstract:We provide a chromosome model YR-cohesion chromosome model.30nm solenoid fold and bent through JW-ladder and chromonema spiraling to chromosomeIll.It is checked by this calculation of picked ration,length,chromosomal structure and DNA base pairs,which are all consonant with practical resultsIll.YR-cohesion chromosome model will give a better answer to the questions such as exchange,centromere,holocentromere,synaptonemal complex,polytene chromosome,puff,lampbrush chromosome,chromosome banding,non-segregation of sister chromatid,pollentube pathway and biological evolution.
