Answer:
D) splicing together of introns through rna processing
Explanation:
Transcription is the process by which an mRNA molecule is synthesized using a DNA template. However, the initial mRNA transcript is considered pre-mRNA until it undergoes post-transcriptional processing to become matured. The mRNA processing involves three steps viz: capping of 5', polyadenylation and splicing.
The 5' end of the mRNA molecule is capped with a 5' cap in the first mRNA processing stage. This is followed by the addition of a poly(A) tail to the 3' end of the mRNA strand. The last step called Splicing involves removal of introns (non-coding regions of sequence) from the mRNA sequence while the remaining protein-coding regions called EXONS are joined or spliced together.
Hence, option D which says: splicing together of introns through rna processing is not correct because exons are spliced together during splicing step of mRNA processing.
Parkinson's I guess would inhibit parts of the synapses which produce or receive neurotransmitter substances such as dopamine or acetylcholine which are required to produces as EPSP excitatory post synaptic potential which is required for the propagation of nerve signals. so signals cant reach the conscious muscles as effectively causing the involuntary shaking of the muscles in people with Parkinson's
hope that helps
T (time period) = t (times it took for oscillation)/ N (number of times it oscillated)
= 50/25 = 2
