Which of the following is a protein that acts as DNA scissors? answer choices plasmid restriction enzyme ligase protein expression Question 3 60 seconds Q. In addition to the chromosome, bacteria often contain plasmids small circular DNA molecules. Bacteria can pick up new plasmids from other bacterial cells (during conjugation) or from the environment. They can also readily lose them for instance, when a bacterium divides in two, one of the daughter cells might … See more The DNA of most bacteria is contained in a single circular molecule, called the bacterial chromosome. The chromosome, along with several proteins and RNA molecules, forms an irregularly shaped structure called the … See more Every plasmid has its own origin of replication a stretch of DNA that ensures it gets replicated (copied) by the host bacterium. For this … See more Some plasmids take extreme measures to ensure that they are retained within bacteria. For example, some carry a gene that makes a long … See more Keeping a plasmid is hard work for a bacterial cell, because replicating DNA (including plasmid DNA) uses up energy. However, by protecting its bacterial host from stress-related death, a plasmid maximises its … See more can hep a and hep b vaccine be given together
