In the choreography of meiosis—the process responsible for sex cell division in all eukaryotic life—the pairing of homologous chromosomes (homologs) is essential. Errors in this process can lead to an ...

In human cells, DNA carries chemical or "epigenetic" marks that decide how genes will be used in different tissues. Yet in a ...

During sexual reproduction, haploid gametes (i.e. eggs and sperm) are generated from diploid precursors through the specialized cell division of meiosis. Meiosis reduces ploidy by following one round ...

DLGAP5 is proposed as a causal gene related to oocyte meiosis disorder for the first time. It expanded the current spectrum of pathogenic genes responsible for the phenotype of oocyte maturation and ...

During prophase I of meiosis, chromosomes become organized as loop arrays around the proteinaceous chromosome axis. As homologous chromosomes physically pair and recombine, the chromosome axis is ...

A research team at the IPK Leibniz Institute has developed a method that enables the detailed observation of female ...

Biologists developed a method for illuminating the intricate interactions of the synaptonemal complex in the nematode C. elegans. The authors identified a trio of protein segments that guide ...

We have two copies of each chromosome in every cell in our bodies except in our reproductive cells. Sperm and egg cells contain a single copy of each chromosome with a unique mix of genes from our ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...
