Answer:
B. It provides the code for the protein
Explanation:
Remember that mRNA stands for Messenger RNA.
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:
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Various Human Activities That Affect an Ecosystem
Agriculture.
Deforestation.
Overpopulation & Overconsumption.
Plastic Production.
Emission of Carbon Dioxide and Other Greenhouse Gases.
Destruction of the Reefs.
Production of Black Carbon.
Draining Streams/Rivers and Destruction of Critical Freshwater Aquifer Recharge Areas (Water Pollution)

A Nonsense mutation. It changes a codon coding for an amino acid to a codon coding for the signal to stop or terminate translation
Acetylene (C2H2) has a triple bond between the two carbons. So 3 pairs of electrons. Biomed is talking about ethylene (C2H4).
