Destroyer # 54 Biology

Okay, if anyone can explain this question to me and the background behind it because I am lost to how to understand it

54. A scientist does a study on TCA cycle enzymes, She discovers that a gene for dehydrogenase spans over 4000 base pairs of DNA. She discovered that 7 introns, and 11 exons were present. The number of nucleotides most likely to be found in the in the mature mRNA after post transcriptional processing could be?

If I remember correctly all of the answers except one had more base pairs than the original gene. After mRNA processing the introns are spliced out and you are only left with the exons, so the base pairs would be >4000.

@jws95 thats what i was thinking because the anwser is 1150 so i was like do i just look at the other anwser choices and realize that its supposed to be less than 4000? The other choices were 4000, 5250, 15000, and 1

Exactly!
