Answer:
The correct answer is -
Thymine: 20%
Guanine: 30%
Cytosine: 30%
Explanation:
According to Chargaff's rule which states that the purine residues are equal to the pyrimidines residue in DNA sample which means A+G = T+C where A is adenine, G is guanine, C is cytosine and T is thymine. It is also known that A is always equal to T and C is equal to G.
So, A+G+T+C = 100
20+20+G+C
100-40 = G+C
60= G+C
as we know G is equal to C similarly A is equal to T
Thus, G = C= 30%
A= T= 20%
Answer:
The spinal cord functions primarily in the transmission of nerve signals from the motor cortex to the body, and from the afferent fibers of the sensory neurons to the sensory cortex.
Explanation:
Its three major roles are to relay messages from the brain to different parts of the body, to perform an action, to pass along messages from sensory receptors to the brain, and to coordinate reflexes that are managed by the spinal cord alone.
