In a recombinant dna experiment, which enzyme is used to join together dna fragments by forming phosphodiester bonds between nucleotides? recall that this same enzyme joins together okazaki fragments on the lagging strand during dna replication.

The correct answer is DNA ligase.  

DNA ligase can be described as a DNA-joining enzyme. It has a possibility to link two pieces of DNA if they have the matching ends, using ATP as an energy source. As a result, unbroken molecule of DNA is formed. It is used in recombinant DNA experiments, for example, to insert genes and other pieces of DNA into plasmids.

the glands which are associated with each description is given below:

pancreas - is an endocrine and exocrine gland that secretes juices with enzymes for digestion. salivary glands- with protection and digestion in the mouth. liver- secretes bile for digestion.   lachrymal glands - secrete tears to moisten eyes and protect them from particles and infection.   sweat gland -regulates water, salt, and temperature. oil glands - to form a protective barrier on the skin.   goblet cells - secrete mucus for protection.
