Question

33. you start a job as a research assistant and asked to decide on a new model organism to study a human disease. you start by writing a list of valuable charactristics of model organisms. which of the following are advantages of performing research on a model organism?

a. research on model organism often requires more sophistaced equipment and is more expensive than working with human cells.

b. model organisms are simpler to work with because they do not have genes that are conserved which or similar to human genes

c. there are not many tools available for genetic manipulation of model organisms

d. the genome of model organisms are often less complex than human genomes

e. none of the above

Answer 1

The correct answer is option (d). The genome of model organisms are often less complex than human genomes.

Explanation: Model organisms have relatively fewer genes than the human genomes. These makes them less complex to study. Moreover, many of these genes are conserved throughout evolution. So, they can be studied in the model organisms effectively. Research on human cells require extensive expertise as they are difficult to maintain. Whereas, model organisms could be worked easily using simple biological techniques. Their maintainence and growth is easier than human cell culturing. Numerous biological tools are available to manipulate the genes of model organisms. They can be easily tweaked and used for experiments according to the needs of researcher.
