Minichromosomes can be either linear or circular pieces of DNA. [3] By minimizing the amount of unnecessary genetic information on the chromosome and including the basic components necessary for DNA replication (centromere, telomeres, and replication sequences), molecular biologists aim to construct a chromosomal platform which can be utilized to insert or present new genes into a host cell.
Two classes of mcm mutants were identified: Those that affected the stability of all minichromosomes and others that affected the stability of only a subset of the minichromosomes. The former were mutants defective in chromosome segregation such as mcm16, mcm20 and mcm21.
These circuits can serve as a method to modify cellular functions, create cellular responses to environmental conditions, or influence cellular development. By implementing rational, controllable logic elements in cellular systems, researchers can use living systems as engineered "biological machines" to perform a vast range of useful functions ...
Researchers have developed an inexpensive blood test that they say can detect pancreatic cancer — even in its early stages.. Using a small blood sample, researchers from Oregon Health & Science ...

Therapies based on CRISPR–Cas3 gene editing technology delivered by engineered bacteriophages could be used to destroy targeted DNA in pathogens. [194] Cas3 is more destructive than the better known Cas9. [195] [196] Research suggests that CRISPR is an effective way to limit replication of multiple herpesviruses.
