zygotene वाक्य

उदाहरण वाक्य

1. In mice, leptotene, zygotene and early pachytene are enriched for FANC proteins.
2. When the PMCs are in leptotene-zygotene, very few tapetal nuclei are in endomitosis.
3. At the transition to the zygotene stage the telomeres usually aggregate at a nuclear envelope sector, thereby forming a meiotic bouquet.
4. During zygotene phase of prophase I, the chromomeres of homologs align with each other to form homologous rough pairing ( homology searching ).
5. Previous to the pachytene stage, during leptonema, the lateral elements begin to form and they initiate and complete their pairing during the zygotene stage.
6. In the non-mutant mouse, FANCG protein is expressed in spermatogonia, preleptotene spermatocytes and spermatocytes in the leptotene, zygotene and early pachytene stages of meiosis.
7. Irradiation during the leptotene-zygotene stages of meiosis, that is, prior to the pachytene period in which crossover recombination occurs, was found to increase subsequent chiasma frequency.
8. In the non-mutant mouse, FANCD2 is expressed in spermatogonia, pre-leptotene spermatocytes, and in spermatocytes in the leptotene, zygotene and early pachytene stages of meiosis.
9. Similarly, in the grasshopper " Chorthippus brunneus ", exposure to X-irradiation during the zygotene-early pachytene stages caused a significant increase in mean cell chiasma frequency.
