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.

Epigenome editing or epigenome engineering is a type of genetic engineering in which the epigenome is modified at specific sites using engineered molecules targeted to those sites (as opposed to whole-genome modifications). Whereas gene editing involves changing the actual DNA sequence itself, epigenetic editing involves modifying and ...
Engineering biology is the set of methods for designing, building, and testing engineered biological systems which have been used to manipulate information, construct materials, process chemicals, produce energy, provide food, and help maintain or enhance human health and environment.
Live recombinant vaccines can be administered via orally or nasally, instead of injection. Common examples of vaccines with the aforementioned route of admission include the oral polio vaccine and the nasal spray influenza vaccine. [3] [4] These vaccines can stimulate mucosal immunity and eliminate adverse effects associated with injection. [5]
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.
A pUC19 cloning vector showing the multiple cloning site sequence with restriction enzyme sites. A multiple cloning site (MCS), also called a polylinker, is a short segment of DNA which contains many (up to ~20) restriction sites—a standard feature of engineered plasmids. [1]
Cells engineered to fluoresce under UV light. Cell engineering is the purposeful process of adding, deleting, or modifying genetic sequences in living cells to achieve biological engineering goals such as altering cell production, changing cell growth and proliferation requirements, adding or removing cell functions, and many more.
