In the brachial plexus, the posterior cord contains portions of the radial and ulnar nerves.
The brachial plexus is a network of nerves that originate in the spinal cord and innervate the upper limb. It is made up of five roots (C5-T1), three trunks (superior, middle, and inferior), and five cords (lateral, posterior, and three anterior cords).
The posterior cord is one of the five cords of the brachial plexus and is formed by the posterior branches of the upper and middle trunks. It contains fibers from the C8 and T1 spinal nerves and gives rise to the radial and ulnar nerves. The radial nerve innervates the muscles of the posterior arm, posterior forearm, and posterior hand, and the ulnar nerve innervates the muscles of the medial arm, medial forearm, and hand.
The median, musculocutaneous, and radial nerves are not present in the posterior cord of the brachial plexus. The median nerve is a branch of the anterior cord, and the musculocutaneous and radial nerves are branches of the lateral cord.

The right answer is option a. Food first enters our bodies through the mouth before moving through the oesophagus and ending up in the stomach. After leaving the stomach, it moves into the small intestine and then the large intestine.
The GI tract is made up of multiple hollow organs that link to one another from the mouth to the anus. The hollow organs that make up the GI tract are the anus, small intestine, large intestine, and stomach. The part of your digestive process that receives food from your mouth is called the pharynx, which is located in your throat.

Answer A is the right choice. A specific tRNA molecule's anticodon complements the corresponding mRNA codon.
The mRNA molecule's matching codon and the anticodon of the tRNA are complementary. As a result, complementary base pairing allows the tRNA to bind to the mRNA codon. The appropriate mRNA codon and the tRNA anticodon are hence complementary. A trinucleotide sequence called an anticodon is found at one end of a transfer RNA (tRNA) molecule and is complementary to a corresponding codon in an mRNA sequence.
The tRNA molecules are in charge of pairing amino acids with the proper codons in the mRNA. Each tRNA molecule has two separate ends; one of them attaches to a particular amino acid, while the other one binds to the appropriate mRNA codon.
Therefore, we might conclude that Answer A is the best option. The complementary mRNA codon of a particular tRNA molecule is its anticodon.
