The answer would be Down syndrome.
Down syndrome is a disease that caused by trisomy(three chromosomes) of chromosome 21. The number of chromosome in normal condition is two so an extra copy makes the chromosome count become three. The patient will show a sign of men tal retar dation with a few typical characteristic in their faces(facies).
No, not really because if nothing is near them they cant sense any type of danger. But if something is close they may be afraid but don't sense danger. It basically a spiderman myth.

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.
