The given DNA strand for cystic fibrosis is 5'......ATAGCAGAGCACCATTCTG.....3'. Its complimentary DNA strand in 3'......TATCGTCTCGTGGTAAGAC......5'. The DNA strands of 5'.....CAGAATGGTGCTCTGCTAT........3′. The dots before and after the given sequence represent that the given strand is a shirt stretch of the DNA made of large number of nucleotides.
