Almost positive diagram A is a animal cell that’s eukaryotic, and Diagram B is a plant cell that’s also eukaryotic.
Answer:
Transcription, 5' cap addition, addition of poly-A tail, exon splicing, passage through nuclear membrane
Explanation:
After being synthesized during the transcription, mRNA (pre-mRNA) must be modified in order to be functional (mature mRNA) and exported from the nucleus for the process of translation.Modification of pre-mRNA include:
- 5' capping-addition of 7-methylguanosine to the 5' end which protects the pre-mRNA
- addition of adenine residues to form a poly(A) tail whic is also with protective role (from ribonuclease digestion)
- RNA splicing-excision of introns and reconection of exons
Modified mRNA can now be transported from the nucleus into the cytoplasm.
Answer:a negative impact is global warming due to the over use of fossil fuels. a positive impact is the way we control the food chains and keep overpopulation from other species from happening.
