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 ...
Genomic DNA is organized into chromatin via nucleosomes, regulating its accessibility for critical biological processes such as transcription, replication, and epigenetic modification. The dynamic ...
To fight viruses, bacteria have evolved a way to make new DNA without copying it.
