Question

Which mRNA sequence is the complement to the DNA sequence GATCACMany different types of mutations can occur within the body. Cystic fibrosis is a genetic disorder that is caused by different mutations within the CFTR gene. One mutation in the CFTR gene that leads to cystic fibrosis causes translation to end earlier in the gene sequence. Which type of mutation causes this translation error that leads to cystic fibrosis

Answer 1

Answer:

The mRNA sequence that complements the DNA sequence GATCAC is CUAGUG.

Explanation:

A is adenine, which in DNA, pairs up with Thymine.

In mRNA, A pairs up with U, Uracil. Uracil is simply Thymine's replacement in mRNA.

In both mRNA and regular RNA, G, Guanine, and C, cytosine, always pairs up.

To find the sequence, I followed the sequence, but just switched it up with its pairs, getting CUAGUG from GATCAC.

Hope this helped and good luck :)
