Modern ideas about the appearance of chromosomesmay undergo significant changes after the publication of the study by scientists working at Harvard University. Based on the research data, the chromosome is not always an X-shaped structure.
Using a new 3D imaging system withBy integrating multiple snapshots of genomic loci along DNA strands, the researchers were able to visualize chromosomes in the highest degree of detail. According to the research, up to 90% of the time, the shape of the chromosomes does not correspond to the X-shaped structure, which is manifested only after DNA replication, until the end of the cell division process.
Using the latest methods of 3D visualization of chromosome structure will help to understand how it controls the process of genome functioning.
