Question 4 (1 point)<br> Why are nonsense mutations rare?
Lostsunrise [7]

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.

How many possible outcomes exist when two fair coins are flipped and a three-section spinner is spin??
Ganezh [65]
9 possible outcomes.

1. There are two coins being flipped.
Possibilities:
HH (two heads) HT (heads and tails) TT (two tails)

There are three sides to the spinner
Possibilities:
Side 1     Side 2    Side 3

Since there are 3 possibilities for each, multiply them together
So, 3*3 which equals 9 possibilities

Circulatory system summary
inna [77]

Answer:

The circulatory system or vascular system is an organ system that helps in the transport of the blood from and to the heart. The blood transport also takes oxygen, nutrients, hormones, and other components from the heart to the various part of the brain with the help of the arteries and carry waste such as carbon dioxide to the heart in veins.

The oxygenated blood enters in the left atrium and moves to the left ventricle to the aorta and starts its journey to the body whereas deoxygenated blood enters in the right upper chamber or right atrium of the heart and pump to the right lower chamber and to the lungs to carry the oxygen again. This process is a continuous process.
