When a DNA sequence alteration results in a stop codon rather than a codon that specifies an amino acid, it is known as a nonsense mutation. This is rarely seen in 10% of patients with genetic disease.
<h3>What is nonsense mutation?</h3>
A nonsense mutation in a DNA sequence causes a premature stop codon, also known as a nonsense codon, in the transcribed mRNA as well as a shortened, ineffective, and typically nonfunctional protein product.
Because stop codons, also known as nonsense codons, signal the completion of protein synthesis rather than encoding for an amino acid, they are the source of the term "nonsense mutation."
Examples of illnesses for which nonsense mutations have been implicated as contributing factors include: Cystic fibrosis (produced by the G542X mutation in the cystic fibrosis transmembrane conductance regulator); (CFTR) Beta-globin (thalassemia) Hurler disease.

Answer is Chromosomes have coiled and become more compact. Please mark as the brainliest answer if it helped.
The cell contains many nuclei containing DNA, so DNA synthesis and mitosis are taking place, but the cell is not undergoing cytokinesis.
The answer is young child.
Nasal regurgitation it's when the food regurgitates out of the nose.
This is more likely to occur in babies/ young children with some birth defects in the soft palate, or if they have a cleft lip. Those birth defects, usually, get fixed with surgery when they are still children, that's why is less frequent after that age.
