Question from alternative source
Numerous mutation types can arise in the body. Cystic fibrosis is a genetic condition attributed to various mutations in the CFTR gene. A specific mutation in the CFTR gene related to cystic fibrosis results in an earlier-than-expected termination of translation in the gene sequence. Which kind of mutation leads to this translation error resulting in cystic fibrosis?
- silent
- missense
- nonsense
- deletion
Answer:
Nonsense
Explanation:
Nonsense mutations refer to those that create a premature stop codon. The stop codons include UAG, UAA, and UGA. This situation could occur if a nucleotide substitution happens in the mRNA codon UAC (which codes for the amino acid Tyrosine) changing to UAG (which signifies a stop codon).
Upon reaching this codon, the translation machinery would interpret it as a directive to end translation. Consequently, the mRNA would be released, leading to a truncated version of the amino acid, which is likely not functional and could be flagged for destruction by the cell.
The antidote functioned by repairing and healing his cells. An antidote serves to cure an individual from illness or toxins.
Streptomycin, which is derived from certain bacteria and fungi, is utilized to combat bacterial infections (prokaryotic), including tuberculosis and mycobacterial infections. This antibiotic disrupts protein synthesis in prokaryotes as it impacts the operation of 70S ribosomes, which are essential for the production of proteins. It has no effect on eukaryotic cells since it does not attach to their ribosomes, hence leaving their protein synthesis unaffected.
The nurse must take steps to limit the amount the child absorbs into their system. Additionally, the nurse should promote the elimination of any toxins ingested by the child while providing necessary supportive care.
The new nucleotides align correctly with those on the complementary strand
