Answer:
d) a polypeptide missing an amino acid.
Explanation:
Deletion is a type of mutation when one or more codons from the reading frame are removed. This results in the production of a relatively shorter mRNA that lacks one or more codons otherwise present in the non-mutated mRNA. When there is a deletion of a single codon in the gene for cystic fibrosis, the resultant shorter mRNA codes for a polypeptide chain that does not carry one amino acid. For example, deletion of one codon results in deletion of a Phe residue present at position 508 in CFTR. The mutated transmembrane protein CFTR folds in an improper way.
Answer:
DNA is being transcribed into mRNA

Answer:
If a female child has hemophilia it is possible that the mother is a carrier of the hemophilia gene and the father has hemophilia.
Explanation:
- A daughter gets X chromosome from both her parents.
- It is generally seen in males.
- Hemophilia is generally recessive in females.They act as carriers of hemophilia. This occurs because they have a X chromosome that dominates the hemophilia affected gene that they inherit from any parent.
- But, if both the parents have faulty genes ,i.e the mother is the carrier of the gene and the father is hemophiliac, then the chances are the daughter has hemophilia too.
