The major chromomeres of pachytene chromosomes 6 and 11 in the oocytes of Acheta (Orthoptera) are regions of amplification for ribosomal RNA cistrons (28 S and 18 S). During late prophase the amplified DNA copies are released from the chromomeres, which decrease in size as the amount of DNA decreases. The number of nucleotide pairs released from the major chromomere of chromosome 11 is about 1.38 x 10(9).
在蟋蟀（直翅目）卵母细胞中，粗线期染色体6和11的主要染色粒是核糖体RNA顺反子（28 S和18 S）的扩增区域。在前期晚期，扩增的DNA拷贝从染色粒中释放出来，随着DNA量的减少，染色粒的大小也随之减小。从染色体11的主要染色粒释放出的核苷酸对数量约为1.38×10⁹。
