||
|
The Branchpoint A in the intron would be unable to attack its splice site, so no splicing would occur at this location |
||
|
No changes would occur |
2) iPSCs are identified by the production of a protein called Fbx15. This protein is specifically produced in pluripotent stem cells, so it can be used as a marker of pluripotent cells. What types of modifications will the Fbx15 mRNA undergo before it is ready for translation?
|
Nucleotides will be added. |
||
|
Nucleotides will be removed. |
||
|
Both (a) and (b) are correct. |
||
|
None of these will occur. |

Genes in eukaryotes are often organized into exons and intrans, which require splicing to produce an mRNA that can be translated. The gene organization is the order of the DNA segments that comprise the gene starting with the promoter, the first exon, the first intron, the second exon, and so on. The interspersed intrans can make gene identification difficult in eukaryotesparticularly in higher eukaryotes with many introns and alternative spliced mRNAs. Prediction of many genes and their organization has been...
