Normally, the three DNA base pairs A-T-C (paired with T-A-G on the opposite strand) at the gene's 507th position form the template for the mRNA codon A-U-C for isoleucine, while the three DNA base pairs T-T-T (paired with A-A-A) at the adjacent 508th position form the template for the codon U-U-U for phenylalanine.[2] The ΔF508 mutation is a deletion of the C-G pair from position 507 along with the first two T-A pairs from position 508, leaving the DNA sequence A-T-T (paired with T-A-A) at position 507, which is transcribed into the mRNA codon A-U-U. Since A-U-U also codes for isoleucine, position 507's amino acid does not change, and the mutation's net effect is equivalent to a deletion ("Δ") of the sequence resulting in the codon for phenylalanine at position 508.[3]

So it does effect 2 pairs, but only has a net change of deleting the 508th protein

Loved the video, really helped with understanding for me. If you don't mind wondering, what source did you use? I'm just wondering if I can use this for a school assignment. Thanks!

Hi everybody, I'm a writer living with CF, and if you like to read, I want to invite you to check out my book. If it sounds like a good read to you, please check it out. I'm working on my next one now!!! Thank you for the support! http://www.amazon.com/Christopher-C.-Byrne/e/B00NHH9176/ref=dp_byline_cont_pop_book_1
