Answer:
Central banks control and manipulate the national money supply: issuing currency and setting interest rates on loans and bonds.
Explanation:
To ensure a nation's economy remains healthy, its central bank regulates the amount of money in circulation. Influencing interest rates, printing money, and setting bank reserve requirements are all tools central banks use to control the money supply.
Answer:
Decide what traits you'd like to amplify or get rid of.
Answer:
DNA from a gene of interest can be inserted into a plasmid, then the modified plasmid can be inserted into a bacterial cell to replicate a gene of interest many times.
Explanation:
Plasmids are the extra-chromosomal circular DNA present in bacterial cells. Plasmids are able to replicate themselves independent of genetic DNA. Their ability to self replicate allows them to maintain themselves in the bacterial cells. This is why plasmids are used as cloning vectors in recombinant DNA technology.
A gene of interest is isolated from the donor cell and is inserted into the plasmid. The recombinant plasmid is introduced into bacterial cells where it replicates the ligated desired gene and allows the gene cloning. For example, the human insulin gene is ligated with plasmid and the recombinant plasmid is introduced in <em>E. coli</em> where it replicates the human insulin gene and allows the production of desired copies of the gene.
