How is all of that DNA packaged so tightly into chromosomes and squeezed into a tiny nucleus? Histones are a family of small, positively charged proteins termed H1, H2A, H2B, H3, and H4 (Van Holde ...
Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For ...
Researchers analyzed the ancient DNA of two mummies from what is now Libya to learn about people who lived in the "Green ...
For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process ...
DNA analysis is crucial for identifying individuals and their relatives, using technologies like PCR, electrophoresis, and ...
引言你可能还记得在生物课本上见过的,细胞分裂时那清晰的X形染色体,它们是生命密码的载体,在细胞分裂过程中扮演着至关重要的角色。然而,你是否曾好奇,这些看似简单的“小棍子”是如何从长长的DNA分子,一步步折叠、浓缩成如此高度有序的结构?长期以来,研究人 ...
By analyzing the flowerpot snake's unique genome, scientists are uncovering how the tiny reptile repairs its DNA and prevents harmful mutations. The findings provides valuable insights into genetic ...
Scientists at EMBL have captured how human chromosomes fold into their signature rod shape during cell division, using a ...
为探究基因组 DNA 在有丝分裂时如何折叠成杆状染色体,欧洲分子生物学实验室研究人员开展相关研究,发现其通过凝缩蛋白(condensin)挤出重叠环及自排斥形成,为理解遗传信息传递提供依据。
Researchers at the University of Texas at Arlington discovered how the flowerpot snake, with three sets of chromosomes, can ...
Cell aging has always been an important topic in biological research, and telomere shortening is one of the key issues in ...
Utrecht University has appointed Bas van Steensel as Special Professor of Chromosome Biology. Van Steensel will lead fundamental research into how chromosomes function and how genetic information is ...
