yes
yes, it is caused by a mutation in the gene cystic fibrosis transmembrane conductance regulator (CFTR). The most common mutation, which results in a loss of the amino acid phenylalanine
cystic fibrosis
In the DNA: a mutation on chromosome 7
The gene on chromosome 7 produces a protein called cystic fibrosis trans-membrane regulator. Mutation in the DNA level of chromosome 7 leads to the absence of this protein which leads to cystic fibrosis. Cystic fibrosis is a recessive disease.
No, cystic fibrosis is an autosomal recessive disorder.
Polygenic means influenced by multiple genes. Cystic fibrosis is a single gene disorder, in which a mutation occurs in one gene that specifies cystic fibrosis, in this case CFTR gene. There are thousands of possible mutations in this gene but the most common mutation is the deletion of one codon.
No. Cystic fibrosis is an autosomal recessive disease. Each parent would have to be a carrier of a CF mutation and would be Cc.
Yes, it is caused by a mutation in the gene for the protein CFTR.
False.
The genotype of a person with CF is cc. The genotype of a carrier of a CF mutation is Cc.
It is caused by a gene mutation in the single gene on chromosome 7 that produces a protein known as CFTR.
