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.
A higher temperature gradient causes faster heat transfer, and thus faster convection currents. If the core were cooler, the temperature gradient would be lower, so the convection currents would likely slow down.
Answer:
C: Converting radiant energy into chemical energy.
Explanation:
Only plants (producers) in a typical ecostystem can convert radiant energy into chemical energy.
A. Kidneys are the organs in the urinary system that produce urine after breaking it down from food.
