Genomes are the blueprints of living creatures; chromosomes and genes within all our cells encode information about life. Genome editing technology that can change these chromosomes and genes has developed rapidly. From drug development and gene therapy, improvements to crops and livestock, to creating useful microorganisms to replace petroleum, this technology has started to have a significant impact on our societies.

Professor NISHIDA Keiji (Graduate School of Science, Technology and Innovation) has developed a new genome editing technology and established a business venture based on his research findings. He is on the front lines of genome editing in both business and research.

What’s up with the fourth dimension? Neil deGrasse Tyson and Chuck Nice explore the dimensions, worldlines, and what it would mean to be 4D.

Learn about time and space and how we navigate through both. What would a 2D world be like for two-dimensional people? We break down what it’s like for 3D beings to interact with the second dimension and what it would be like for 4D beings to interact with the third dimension. Plus, we discuss flying cars and whether we already have them.

“Trillions of cells in our body divide every single day, and this requires accurate replication of our genomes. Our work describes a new mechanism that regulates protein stability in replicating DNA. We now know a bit more about an important step in this complex biological process.”

An enduring mystery of ‘lagging strand’ DNA replication

The DNA replication process is carried out by multiple protein complexes with highly specialized functions, including the unwinding of DNA and the copying of the two unwound DNA strands. The process is akin to a factory assembly line where balls made up of massive, crumpled strings of data are unraveled, allowing specific pieces to be trimmed and copied. Biologists know a good deal about how this process starts and proceeds, but know less about how it is stopped or paused.
