After reading the paragraphs below, answer the questions that follow.

Researchers are using the CRISPR-Cas9 system to genetically engineer organisms in order to study gene function and to attempt to help patients with genetic diseases. In 2016, a research team used the CRISPR-Cas9 system to genetically alter pig zygotes so that they would have muscular dystrophy, a type of genetic disease that results in muscle wasting and loss of muscle mass. This disease often results from a lack of the protein dystrophin in skeletal muscle tissue. Researchers sometimes develop animal models of diseases so that they can develop therapies to treat the human version of the disease.
The researchers compared the molecular biology and physiology of two types of pigs: healthy, normal pigs (WT) and those that were modified when they were zygotes with the CRISPR-Cas9 system (CRISPR). The data below show the dystrophin levels in various tissues from both types of pigs.

Porcine zygote injection with Cas9/sgRNA results in DMD-modified pig with muscle dystrophy. International Journal of Molecular Sciences,17(10): 1668. MDPI AG. Retrieved from http://dx.doi.org/10.3390/ijms17101668.


In this study, what would have been true of the guide RNA that was used in the CRISPR-Cas9 system?
◦ The guide RNA helped target the Cas9 enzyme to the dystrophin protein.
◦ The guide RNA was injected into skeletal muscle cells, heart cells, and intestinal cells.
◦ The guide RNA was complementary in sequence to a region of the dystrophin gene.

Did you know?

In 1886, William Bates reported on the discovery of a substance produced by the adrenal gland that turned out to be epinephrine (adrenaline). In 1904, this drug was first artificially synthesized by Friedrich Stolz.

Did you know?

Hip fractures are the most serious consequences of osteoporosis. The incidence of hip fractures increases with each decade among patients in their 60s to patients in their 90s for both women and men of all populations. Men and women older than 80 years of age show the highest incidence of hip fractures.

Did you know?

Throughout history, plants containing cardiac steroids have been used as heart drugs and as poisons (e.g., in arrows used in combat), emetics, and diuretics.

Did you know?

An identified risk factor for osteoporosis is the intake of excessive amounts of vitamin A. Dietary intake of approximately double the recommended daily amount of vitamin A, by women, has been shown to reduce bone mineral density and increase the chances for hip fractures compared with women who consumed the recommended daily amount (or less) of vitamin A.

Did you know?

Vampire bats have a natural anticoagulant in their saliva that permits continuous bleeding after they painlessly open a wound with their incisors. This capillary blood does not cause any significant blood loss to their victims.
