Answer:
For involuntary actions (reflexes) the information is first detected in the sensor and travels along sensory neurons to the spinal cord. Once the action potential reaches the spinal cord, the information is transmitted across the synapse to the motor neuron. for voluntary actions,
movements are commanded by the motor cortex, the zone of the cerebrum located behind the frontal lobe. The motor cortex sends a neural message that moves through the brain stem along the spinal cord and into the neural network to the muscle being commanded.
The amino acids coded triplets in the 3' to 5' strand on the normalp53 gene of chromosome 13 are lysine, leucine, Glutamine, stop codons.
Explanation:
mRNA is formed by the transcription of DNA strand coding for a gene.
Any mutation in the DNA sequence even a difference of base pair would cause formation of different amino acids and hence altered protein.
The amino acid is formed in the step of translation where codes are read by tRNA on the mRNA strand and correct nucleotide is brought to growing polypeptide chain.
In transcription 3' to 5' strand acts a template strand. The amino acids on the p53 gene of chromosome 17 is
3'TTT AAC GTC ATC 5' Gene sequence
5' AAA UUG CAG UAG 3' mRNA
lysine, leucine, Glutamine, stop
