Question

A cultured cell line appears to be having trouble surviving. Upon closer examination, you find that the cells do not appear to have normal chromosome separation. Based on this observation, you decide to check for the presence of a mutated protein. You will be sure to analyze the gene for which protein?

Answer 1

Answer:

Tubulin

Explanation:

Tubulin is a globular protein with a molecular weight of approximately 55 kDa and is found in almost all eukaryotic cells. There are 5 types of tubulin, called α-tubulin, β-tubulin, γ-tubulin, δ-tubulin and ε-tubulin, but α- and β-tubulin are by far the most common forms of tubulin. Tubulin is the subunit that makes up the microtubules that, in turn, form an integral part of the cytoskeleton with essential functions in transporting cellular components within the cell and in cell division itself.

In the case of the above question, as cells do not appear to have normal chromosomal separation, this may have been caused by problems in the formation of microtubules, so it would be better to analyze the gene responsible for tubulin.
