Question

The advantage of yeast cells over bacterial cells to express human proteins is that:

a) Yeast cells are smaller
b) Yeast cells lack cell walls
c) Yeast cells are eukaryotic
d) Yeast cells divide more slowly

Answer 1

Yeast cells are preferred over bacterial cells for expressing human proteins because they are eukaryotic organisms that share closer genetic regulating mechanisms with humans, making them advantageous for recombinant DNA technology.

Step-by-step explanation:

The advantage of yeast cells over bacterial cells to express human proteins is that yeast cells are eukaryotic. Yeasts, unlike bacteria, contain a nucleus and have a similar system for genetically regulating mechanisms. As eukaryotic organisms, yeast cells produce and modify proteins in ways that are more closely aligned with human cellular processes. This includes having internal membrane structures and enzymes that are akin to those in human cells, which are critical for tagging proteins for export. Yeasts are also amenable to genetic modification and can grow easily in culture with a short generation time.
