The most commonly occurring mutation in people with cystic fibrosis is a deletion of a single codon. This results in:__________

Biology

4 0

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.

What amino acid sequence does the following dna nucleotide sequence specify? 3′−tacagaacggta−5′.
Oduvanchick [21]

The amino acid sequence for the following DNA sequence is Met-Ser-Cys-His.

<h3>What is transcription and translation?</h3>

Transcription is the process of conversion of genetic information carried by the DNA into messenger RNA (mRNA).

  • Sense strand of DNA is the one which runs in 5’ to 3’ direction and carries the information while antisense strand runs in 3’ to 5’ direction and serves as a template.
  • E.g.: Antisense strand 3′−TACAGAACGGTA−5′

               mRNA sequence 5’−ATGTCTTGCCAT−3’

Translation is the process of conversion of information carried by the mRNA into an amino acid sequence.

  • The genetic code is read as a sequence of 3 nucleotides together at a time and is called codon.
  • For example: 'ATG' is a start codon coding for methionine.

        Here, mRNA sequence 5’−ATGTCTTGCCAT−3’

        Amino acid sequence: Met-Ser-Cys-His
