Deciphering the Mystery of Unsolved Gene Replication in Sixty Years |
DNA replication sequence maintains cell epigenetic state |
Science and Technology Daily, Beijing, April 27th (Intern reporter Zhang Jiaxin) According to a recent study published in the journal Science, a research team led by Dr.
In the past 60 years, scientists have been able to observe how and when genetic information is replicated, and have determined the existence of a "replication sequence program", which controls the time and sequence of DNA fragment replication, but still can’t explain why this is the case.
Dr.
The research team has previously discovered that each type of cell has a unique replication sequence, and diseased cells have significant changes in this process.
They found that a protein called Rif1 helps regulate DNA replication.
Dr.
"Previously, we have proved that the replication sequence program changes in many diseases.
