You are a researcher working on a treatment for Hutchinson-Gilford progeria syndrome, an extremely rare genetic disorder that ca

uses accelerated aging in children. Children with progeria generally appear healthy at birth but soon start growing more slowly than other children and lose their hair. Additional symptoms include stiffness of joints, heart problems, and stroke. These children typically die of heart disease at an average age of 13 years.
Progeria is caused by a mutation in a single gene, called lamin A. Scientists have identified over 1,400 mutations in the lamin A gene that result in changes in transcription, RNA splicing, and/or protein production. Lamin A codes for a protein required for the structural support of the nuclear envelope in cells. Without a functional protein, the nuclear envelope becomes unstable, eventually damaging the nucleus and causing cells to die.

Based on what you learned in this Click & Learn, propose a genetic medicine strategy you could develop to treat patients with progeria. Describe which step in gene expression you might target and why you would target that step, the intervention tool you would use, and explain how this strategy would treat the disease

Answer:

If predominantly, we can't say of any treatment for progeria, aside from the routine observation of heart and blood vessel (cardiovascular) disease which is important in taking care of the health situation in the affected kids. Treatment relies majorly on the situation and clinical manifestations of the kid. At first, in 1999, the findings of the initial clinical drug trial for kids with an unusual rapid-aging disease, often referred to as Progeria, revealed positive results with a farnesyltransferase inhibitor (FTI), a drug initially designed to treat cancer.

The PATHWAY in gene expression to be TARGETED is progenin formulation---

The Progeria-forming mutation results in the formation of the protein progerin that disrupts the cell activities. Some areas of progerin's toxic impact on the body is due to the formation of a farnesyl group, Â that adheres to the progerin protein aiding it's disruption of the body's cells. FTIs means of action is through inhibition of the adhesion of the farnesyl group to progerin, decreasing the hazardous substances that leads to progerin.

The genetic medicine technique that acts as.an intervention tool gene therapy to regulate the gene that causes the stimulation and formation of the protein progenin.

Escalated cardiovascular disease results in death in the case of Progeria.

It's worthwhile to note that if the basic blood vessels can with time get better as a result of treatment, the treatment shows positive results. Slowing down stroke and aging manifestations will boost the chances of treatment.

A mutation in a gene in the fruit fly Drosophila was found to affect eye color. The protein affected was found to be completely
lilavasa [31]

Answer:

The correct option is D. A reasonable explanation for the change in levels of protein is that the mutation occurs in the promoter of the gene, within several hundred base pairs of the start of transcription.

Explanation:

In genetics, a promoter can be described as a region where the RNA polymerase binds initially and starts transcription. The promoter is usually present near to the gene that has to be transcribed. The rate of transcription is controlled by the promoter region too. Hence, the correct option is D. The promoter region for the eye colour was changed due to mutation.

Other options are false because a change in a codon or base pair would have changed proteins being formed and would not have slowed the process.

Dentify the relationships between the zooxanthellae and the hard coral, the remora and the manta ray, the tiger shark and the gr
sergeinik [125]

Answer:

1. Mutualism

2. Mutualism (it was previously thought to be a case of commensalism)

3. Predation

4. Competition

Explanation:

<u>1. Zooxanthellae and hard coral - </u><em><u>Mutualism</u></em>

These two organisms live in symbiosis. This means that both benefit each other. Zooxanthellae allow corals to gain energy through photosynthesis and, in turn, they receive important nutrients that are produced during the metabolism of the hard coral.

<u>2. Remora and manta ray - </u><em><u>Mutualism</u></em>

Remoras and manta rays benefit each other. Remoras attach to manta rays mainly for transportation and feeding, but they also do it for protection. In turn, they make sure manta rays are clear from harmful bacteria and parasites. Several years ago, it was thought that manta rays didn't gain any benefit from remoras, so this was thought to be a case of commensalism. However, research has shown that they both benefit from each other. Therefore, this is also a case of mutualism.

<u>3. Tiger shark and green sea turtle - </u><em><u>Predation</u></em>

In some areas (not everywhere) tiger sharks feed upon green sea turtles. For example, in Hawaii, have been observed to attack green sea turtles and feed on them. Researchers have spotted numerous sea turtles with characteristic tiger shark bites.

<u>4. Dolphins and school of trevallies - </u><em><u>Competition</u></em>

Trevallies are large species of fish that feed on small schools of fish like dolphins. They both have their own predatory strategies that involve planning and gathering to catch large amounts of fish. Therefore, trevallies and dolphins compete for small schools of fish.
