Highly repetitive regions of junk DNA may be the key to a newly discovered mechanism for gene regulation. The discovery during the Human Genome Project in the early 2000s that we humans have only ...

Seamless site-directed mutagenesis is an important technique for studying protein functions, tuning enzyme catalytic activities and modifying genetic elements in multiple rounds because it can insert, ...

Through its involvement in gene transcription and heterochromatin formation, DNA methylation regulates how cells interact with their environment. Nevertheless, the extracellular signaling cues that ...
