Fertility and Chromosome Pairing
Darlington5565 described the pachytene pairing in tetraploid Hyacintluis and
Primula, and the exchange of pairing partners in the four homologues to form
quadrivalents. Levan64 subsequently found that most quadrivalents at pachytene
in ...

Meiosis: Current Research
Table 3 Comparison of DNA precursor incorporation into cells at zygotene and
pachytene Zygotene and pachytene cells were each harvested from 20 buds and
divided into 3 groups. One group was exposed to 5 /xc/ml. of [3H]BdUrd; ...
MSUC provides a simple and compellingexplanationfor how chromosomal
asynap- sis causes pachytene arrest and it is certainly a more attractive than the
pachytene checkpoint explanation. However, new studies now show that MSUC
alone ...

Meiosis and Gametogenesis
The amino acid sequence of histone THZB, which replaces most of the somatic
H213 histone in pachytene spermatocytes (Meistrich et al., 1985), is most
divergent in the N-terminal third of the molecule that binds to DNA (Y.-J. Kim er al.
, 1987).

Proteomics of Spermatogenesis
The p53 is expressed during meiosis in nonnal rat spermatogenesis and its
expression is localized to the preleptotene-early pachytene spermatocytes. The
most prominent expression is in zygotene. In situ hybridization experiments
indicated ...

Cell and Molecular Biology of the Testis
The figure outlines replication events beginning at the premeiotic S-phase and
terminating after pachytene. The precise stage at which replication is completed
has not been determined. zygDNA is the centerpiece of this figure inasmuch as
its ...

microRNAs in Development
The mammalian piRNAs can be divided into two differentially regulated
subclasses of different sizes referred to as pachytene (29–31bp) and pre-
pachytene (26–28bp) piRNAs (Aravin et al., 2007b). Pre-pachytene piRNAs are
expressed in ...
