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.
Answer:
A longitudinal wave is characterized by COMPRESSIONS and RAREFACTIONS.
Explanation:
D. Oxygen
It refers to the pathway by which a chemical element is moved through both the abiotic and biotic compartment of an ecosystem.
