How is all of that DNA packaged so tightly into chromosomes and squeezed ... can be returned to its compact state after transcription and/or replication are complete. When eukaryotic cells divide ...

ATR and ATM kinases are key factors for the surveillance of DNA replication, and prevent chromosome breakage in dividing cells. However, during repair processes, chromosome fragments can be ...

New research shows that DNA replication in early mouse embryos doesn't follow the expected patterns seen in older cells. A ...

However, the idea that replication forks would form at origins of DNA replication and proceed without impairment to copy the chromosomes has proven naive ... to analyze the events that occur after the ...

Each cell with a nucleus contains chromosomes, which are made from DNA Human body cells each contain 23 pairs of chromosomes, half of which are from each parent. So, human gametes (eggs and sperm ...

科技日报北京9月1日电 （记者张梦然）DNA因其标志性的双螺旋结构而广为人知。但澳大利亚加文医学研究所科学家发现，人类基因组还含有超过5万个不寻常的结状DNA结构，称为i-基序。最新一期《EMBO》杂志发表了这些独特DNA结构的第一张综合图谱，揭示了它们在 ...

Chromosomes are thin strands of DNA (deoxyribonucleic acid). A gene is a short length of DNA found on a chromosome that codes for a particular characteristic or protein. Alleles are different ...

Chromosome Dynamics: Although genetic information is encoded in a one-dimensional array of DNA bases, all major DNA processes (replication, transcription and recombination) are controlled by changes ...

We are interested in the mechanism of chromosome replication, a process that is highly conserved across eukaryotes and that involves the duplication of both the chromosomal DNA and its associated ...

An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes. The study ...
