What nerve branches feed into the nerve plexuses?
S_A_V [24]

Answer:

Nerve plexuses are composed of afferent and efferent fibers that arise from the merging of the anterior rami of spinal nerves and blood vessels. There are five spinal nerve plexuses—except in the thoracic region—as well as other forms of autonomic plexuses, many of which are a part of the enteric nervous system. A plexus is a bundle of intersecting nerves, blood vessels, or lymphatic vessels in the human body. These bundles typically originate from the same anatomical area and serve specific areas of the body. Bundles of nerves that form a plexus communicate information to your brain about pain, temperature, and pressure.

Katen [24]

If one wishes to clone a gene using typical restriction endonucleases, how does the restriction endonuclease identify the appropriate cut sites in the genome using the palindromic sequence.

Restriction endonucleases are a family of enzymes usually found in bacteria that cuts DNA  at a specific sequence called recognition site. There are three type of restriction endonuclease Type I, Type II, and Type III.

Each endonuclease recognizes a particular sequence called palindromic sequence which is a sequence that reads the same sequence in both the strands either reading from the 3 prime end or 5 prime end.

The endonuclease cuts the palindromic sequence in such a way that it produces sticky ends.
