Meiotic telomeres play a critical role in chromosome dynamics, facilitating homolog pairing and synapsis through attachment to the nuclear envelope (NE). While these mechanisms are well-documented for standard A-set chromosomes, the molecul...
Ring chromosomes uncovered by optical genome mapping: impact of telomeric-associated regions and reference genome selection on structural variant interpretation [0.03%]
光学基因组测绘发现环状染色体：端粒相关区域和参考基因组选择对结构变异解读的影响
