Human proteins can be produced by cells in the milk-producing mammary glands of transgenic mammals if the regulatory sequence of a milk gene is used to produce the recombinant gene. Why is it important to use the regulatory sequence of a milk gene when constructing a recombinant gene used to produce a human protein secreted in milk

It is important to use the regulatory sequence of a milk gene when constructing a recombinant gene used to produce a human protein secreted in milk because it is capable of increasing or decreasing the expression of specific genes within an organism.

Explanation:

Regulatory Sequence is a segment of a nucleic acid molecule which is capable of increasing or decreasing the expression of specific genes within an organism. Regulation of gene expression is an essential feature of all living organisms and viruses.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
