Question 4 (1 point) Why are nonsense mutations rare?

Biology
1 answer:
Lostsunrise [7]1 year ago
5 0

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.

Anthocyanin is a pigment that gives flowers and leaves purple colors. The M gene codes for a transcription factor (Myb) that pro
eduard

Answer:

Anthocyanin is not produced in the plant cells

Explanation:

Anthocyanin is not produced in plant cells with the genotype mm.

As you can see from the question above, anthocyanin is responsible for the purple color of the flowers. Anthocyanin is encoded by the M gene, which is a dominant gene. Because it is a dominant gene, we know that it will be expressed in plants with the Mm and MM genotype, but will not be encoded by plants with the mm genotype. With this we can conclude that plants that have the mm genotype do not have purple color, because anthocyanin is not produced in the plant cells of these plants, since they do not have the M gene.

Hormones play an important role in regulating blood glucose levels. what is an example of this?
Ber [7]
The human body wants blood glucose (blood sugar) maintained in a very narrow range. Insulin and glucagon are the hormones which make this happen. Both insulin and glucagon are secreted from the pancreas, and thus are referred to as pancreatic endocrine hormones. The picture on the left shows the intimate relationship both insulin and glucagon have to each other. Note that the pancreas serves as the central player in this scheme.  It is the production of insulin and glucagon by the pancreas which ultimately determines if a patient has diabetes, hypoglycemia, or some other sugar problem.(i hope this can help you) :)

Lena [83]

Answer:

light

Explanation:

The above experiment is an investigation on the factors that affect photosynthesis which include carbon dioxide concentration,light intensity and quality,chlorophyll, water and temperature.Light was the independent variable. When the lant is moved to an area where light intensity is low, the rate of photosynthesis decreases.

After the experiment, oxygen gas is produced being a by-product of photosynthesis. Plants that are not adapted to an aquatic environment are not suitable for this experiment. The amount of carbon dioxide dissolved in water is low.
