In humeral fractures, the main nerves in the arm may have been damaged or compressed (by the cast) after manual reduction. The sensory nerve involved in this case is the musculocutaneous nerve which provide sensation in the hands, particularly here in the right hand. Compression by the cast interrupts nerve impulses in the musculocutaneous nerve owing to the loss of sensation and the removal of cast relieves the compression therefore there is regain of sensation.
Answer:
The correct answer will be option-A.
Explanation:
Inverted repeats are the sequence of the nucleotide in a nucleic acid which is identical but arranged in the opposite orientation. The inverted repeat may be separated by some sequence or they may lie adjacent to each other. They can be read the same from the backwards or forward direction.
In the given question since four bases when read from the forward direction is same as reading the sequence from the backward direction like CGAC can be read the same both backward and forward.
Thus, option-A is the correct answer.
