I believe it would be the coordinator because it would be coordinating the response to the stimuli
Answer:
The correct answer is B) Transcription, 5' cap addition, addition of poly-A tail, exon splicing, passage through nuclear membrane.
Explanation:
The transcription process in eukaryotes takes place in the nucleus of the cell and after transcription post-transcriptional modification also takes place in the nucleus which is necessary to guide the mRNA out of the nucleus.
First, the process of transcription takes place in which DNA is transcribed to mRNA by an enzyme called RNA polymerase. After transcription post-transcriptional modifications takes place in the given order.
1. Capping: In capping process 7-methylguanosine is added by capping enzyme at 5' end of mRNA.
2. Polyadenylation: In polyadenylation, many poly-A residues are added at the 3' end of the mRNA called the poly-A tail.
3. Intron splicing: Introns are the non-coding sequence present in mRNA which are spliced out of mRNA and all exons are joined together.
After these post-transcriptional process, the mature mRNA is transported out of the nucleus through the nuclear membrane.
Answer: The atmosphere can handle almost 700 billion tons of carbon in it. The carbon levels are increasing due to industrial revolution.
Explanation:
The overload of the emission of carbon in the atmosphere surprised me. The data was recorded and investigated for 2000 to 2100. Different parameters like ocean water and fossil fuel. The fossil fuel when burn contribute to the release of carbon monoxide and carbon dioxide gas. The oceanic water release the decomposed carbon dioxide by calcium carbonate of coral reefs and respiration of aquatic animals.
