These patterns stem largely from standard chromosomes with archetypal characteristics including homolog pairing and recombination during meiosis, the even partitioning of individual chromatids ...

During meiosis, sister chromatids produced by chromosome duplication are held together by Rec8, a meiosis-specific cohesion protein. Rec8 joins the whole length of the sister chromatids together ...

1 Centromeres are specialized regions of the chromosome where sister chromatids are joined. Kinetochores are protein complexes assembled on the centromere that serve as the attachment points for ...

the chromosome number is reduced in half through similar, but more complex, stages of cell division. During meiosis II, each haploid cell divides its 2 DNA threads (chromatids) between daughter ...

Conversely, transmission of a linear chromosome would allow correct recombination between non-sister chromatids. The authors applied SNP-array genotype analysis and observed that the r(20) was ...

pulverized chromosomes, chromatids breaks, gaps or exchanges, in metaphases. From each cell monolayer, 50 metaphases were at random analysed, but in those samples in which this number was not reached, ...

As the sister chromatids separate from each other and are pulled toward opposite ends of the cell during anaphase, mitochondria are still fully fragmented. During telophase/cytokinesis, chromosomes ...

The template of whole chromosome 5 painting probe ... it is conceivable that NHEJ does not contribute to the end-to-end fusion of sister chromatids during B/F/B cycles. Inhibition of NHEJ eliminates ...

How did humans evolve brains capable of complex language, civilization, and more? The answer could lie in exceptional DNA.

How did humans evolve brains capable of complex language, civilization, and more? Scientists at UC San Francisco recently ...

Dating back 480 million years, octopuses have one of the oldest known sex chromosomes, according to a new study published in Current Biology. The study unveils that octopuses determine their sex ...

Scientists are exploring gene editing as a way to correct trisomy at the cellular level. Using CRISPR-Cas9, researchers ...
