I have a molecular exam I am struggling with an any help would be greatly appreciated.
1. Some retrotransposons and retroviruses integrate preferentially into regions of the chromosome that are (a) packaged in euchromatin and (b) located outside the coding regions of genes that contain information for making a protein. Why might these mobile genetic elements have evolved this strategy?
2. Is this statement TRUE or FALSE? Explain.
“Since introns do not contain protein coding information, they do not have to be removed precisely (meaning, a nucleotide here and there should not matter) from the primary transcript during RNA splicing.”
For #2 I believe that it is true. As long as there is only a a nucleotide here and there that remains there should be no issues when it comes to making a protein. I am unsure though. Once again any help would be greatly appreciated. Thank you.
