The disease starts as headaches and muscle weakness and progresses to cognitive

/in /by

Please see attached document with questions.

Unit 2 Problem set(1).docx

Unit 2 Problem set(1).docx

Dr. Verybad has discovered a new neurodegenerative disease (Verybad disease, VBD).
The disease starts as headaches and muscle weakness and progresses to cognitive
impairment, loss of muscle control, and death. The cause of the disease is currently
unknown and there is no treatment. Dr. Verybad has a hypothesis that this is the result of
a mutation in a gene located on the X chromosome called Don’t Touch This gene 1
(Dtt1). Dr. Verybad wants to sequence the gene to determine if there is a mutation in Dtt1
responsible for the pathogenesis of VBD.
1) If the defect is in Dtt1, what do you predict would be the male to female incidence
of VBD and why? (10 points)
2) If there is a mutation in the sequence approximately 250 base-pairs upstream of
the transcription start sight, what might this mutation be affecting? Propose 1
experiment to investigate this possibility. Explain the protocol, controls, and
expected results. (10 points)
3) If there is a mutation that falls within an intron close to an exon junction, what
might this mutation be affecting? Propose 1 experiment to investigate this
possibility. Explain the protocol, controls, and expected results. (10 points)
4) If there is a mutation within an exon, what might this mutation be affecting?
Propose 1 experiment to investigate this possibility. Explain the protocol,
controls, and expected results. (10 points)
5) If there is a mutation in the 3’ Untranslated region (3’ UTR), what might this
mutation be affecting? Propose 1 experiment to investigate this possibility.
Explain the protocol, controls, and expected results. (10 points)
6) After sequencing the Dtt1 gene, Dr. Verybad found no changes in the gene
sequence. However, he has found that the protein forms aggregates within the
cells that results in plaque formation, neuronal loss, and a spongy look to the brain
tissue. What might the cause of this disease (5 points extra credit, up to a total of

Identify the nutritional needs for a developing embryo and fetus and how to obtain them.

/in /by

Consider the following scenario: The General Secretary of the FDA has tasked you with developing an educational flier on the nutritional needs for a specific stage of life.

Research your topicusingonline sources, such as the Food and Drug Administration or the U.S. Department of Agriculture; and local sources, such as farmers’ markets, for content and nutrition suggestion for the ad.

Create a public service ad, with appropriate images, to be printed in the Sunday edition of your newspaper. Include the following points:

  • Identify the nutritional needs for a developing embryo and fetus and how to obtain them.
  • Identify health concerns or disease associated with poor nutrition during the gestation period.
  • Provide examples of good and bad nutritional choices for baby and mom.
  • Once the baby is born, address the pros and cons of breastfeeding versus formula-feeding.
  • Make recommendations for where readers might search for more information regarding nutrition.  Remember to determine and choose credible sources of nutritional information.

Use a standard word document to complete this assignment.   Both text and images are important to this assignment.

Format the ad, including the images, consistent with APA guidelines.

Include at least two references.
