Q.Recombinant Factor VIII is produced in the ------- cells of the Chinese Hamster a) Liver cells b) blood cells c) ovarian cells d) brain cells

Step 1. Recall the chapter's specific statement on Factor VIII manufacture: recombinant DNA technology was used to produce recombinant Factor VIII in the Chinese Hamster ovary and in baby hamster kidney cells. Step 2. 'Chinese Hamster ovary' cells (commonly abbreviated CHO cells in biotechnology) are ovarian in origin, directly matching option c. Step 3. Rule out the distractors: liver, blood and brain cells are not the cell type named in the text for this specific manufacturing process — blood cells are, if anything, the histori …

Match the named cell line (Chinese Hamster ovary) directly …

• Confusing the recombinant PRODUCTION host (CHO ovarian cells) with blood cells, which were the his …
