American Journal of Botany, Vol. 27, No. 8 (Oct., 1940), pp. 683-686 (4 pages) Metaphase and anaphase chromosomes of the second reduction division of Gasteria spp. hitherto considered as displaying an ...

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 ...

One of the challenges of working with ancient DNA samples is that damage accumulates over time, breaking up the structure of the double helix into ever smaller fragments. In the samples we've worked ...

Researchers at Rice University are making strides in understanding how chromosome structures change throughout the cell's life cycle. Their study on motorized processes that actively influence the ...

The study shows that specific modifications of the chromosome structure also allow manipulations of the way in which genes are recombined during reproduction. "This is especially interesting for plant ...
