In your continued work at BigPharma, you are running additional experiments with previously developed, FDA approved drugs to see if they can be used off-label to assist with the treatment of neurodegenerative disorders. Originally, NeuroStop was developed to attenuate brain damage following stroke, and thus might be a good candidate drug for helping slow neurodegeneration. Presented here are data...

_________<u1-u2<___________
Spinocerebellar ataxia type 1 is a neurodegenerative disease marked by the gradual loss of motor skills and culminating in early death. It is caused by an expanded CAG repeat in the coding region of the Ataxin-1 gene. Fryer et al. (2011) investigated the possible beneficial effects of exercise in treating the disease. They used a mild exercise regimen in a mouse model of the disease (a mouse strain in which the expanded CAG repeat was "knocked in" to the...

Hi, for the question, please fill it yes or no for each part bolded. Susan and Joe were worried. Their little boy, Daniel, had been having an awful lot of bacterial infections and he was barely a year old. It seemed that the antibiotics cleared up one bacterial respiratory infection only to have another follow shortly. The scary thing was that Daniel had just fought off a case of pneumonia caused by Pneumocystis carnii, a fungal infection that was usually...

Which of the following are true of modifying and epistatic genes in regard to genetic diseases? (1) Modifying genes can account for the severity of a genetic disease Modifying genes do not completely mask genes for a genetic disease. Epistatic genes may cause a disease by masking normal genes. The expression of modifying genes can be affected by environmental factors. Select the true statements about sex influenced and sex limited traits: (circle all that apply) (2) Sex-influenced traits and sex-limited traits...

QUESTION 1 Although SARS-CoV-2 is currently a global health threat, how might we turn it into a tool for biotechnology? a. It could possibly be turned into a viral vector against lung cancers b. Its promoters might be used to express genes in lung cells c. Its surface proteins could be used for new epitope tags d. All of the above QUESTION 2 Which of the following are applications of molecular assembly described in this course? a. It can be...

Biological sex is determined by a complex suite of genes, including the SRY gene and the AR gene. These genes impact hormone production, internal and external reproductive anatomy, and sex characteristics. It's important to note that biological sex is different from gender- gender is based on social and cultural ideas of what it means to be a woman or a man. For this project we are focusing only on biological sex. In the HHM Biolnteractive, Sex Verification of Athletes, click...
