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:
Explanation:
Based on what is known about the fetal skeleton and the ossification process it can be said that this occurs due to babies having more of the osteoblasts bone cells. These cell's main function is to lay down new bone material, this therefore creates a thicker harder bone which allows for proper support so that the body can continue growing and become stronger overall.
I would say this is an expository text.
Answer:
Pulmonary circuit
Explanation:
Pulmonary circuit of blood circulation serves to carry the deoxygenated blood from the right ventricle of the heart to the lungs and then returns the oxygenated blood from the lungs to the left atrium of the heart. The pulmonary trunk carries the deoxygenated blood from the right ventricle to the lungs.
The right pulmonary artery and the left pulmonary artery of the pulmonary trunk carry the blood to the right and left lung respectively. After the gaseous exchange, the pulmonary capillaries unite to form venules and finally the pulmonary veins which in turn carry the oxygenated blood to the left atrium.
Weather, climate and seasons are factors that limit the distribution of different species of living beings in ecosystems, influencing survival and reproduction.
<h3>What are the biotic and abiotic factors of an ecosystem?</h3>
Biotic factors are each of the living organisms of an ecosystem and abiotic factors are all non-living ones such as organic and inorganic substances in the system as well as environmental conditions.
Weather, climate, and seasons could affect these factors in altering the distribution of species, but would also decrease primary production, which would affect survival and growth.
Therefore, we can conclude that the weather, climate and seasons are factors that limit the distribution of different species of living beings in ecosystems, influencing survival and reproduction.
