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 E. coli where it replicates the human insulin gene and allows the production of desired copies of the gene.

Vessels draining the myocardium of the heart, open primarily ,into which chamber?

Kitty [74]

Answer:

The vessels draining Myocardium of the heart join to form Coronary Sinus that ultimately opens into THE RIGHT ATRIUM.

Explanation:

CORONARY CIRCULATION:

The heart muscles are called as Myocardium. Circulation of myocardium is known as Coronary Circulation. The heart needs to work continuously and requires an uninterrupted supply of blood.

Coronary Arteries supply oxygen rich blood to the myocardium and Coronary Veins remove deoxygenated blood from heart muscles and join to form Coronary Sinus that ultimately drains into the Right Atrium of heart. Some veins from the myocardium also drains directly into the right atrium.

The movement of ocean currents around the globe? Check all that apply. Strong winds force warm water to sink to the ocean floor.

zysi [14]

Answer:

Cool dense water sinks to the ocean floor.

Warm water replaces cool surface water.

Wind blowing parallel to the shore causes upwelling of cool water.
