cells within platypusspurs use snake - like venom dna to make toxic proteins. if all platypus cells have the same dna, why dont all the cells make venom?
select the incorrect response
a only cells involved with venom, turn on the gene
b not all cell types express the same genes of the organisms genome
c not all cells contain the venom dna
d most platypus cells have the venom gene turned off.

Explanation:

• Option a: Cells involved with venom turn on the gene, which is a correct concept in gene expression regulation.
• Option b: Different cell types express different genes from the genome, which is a fundamental principle in cell - type specialization.
• Option c: The problem states that all platypus cells have the same DNA. So, the claim that not all cells contain the venom DNA is incorrect.
• Option d: Most cells having the venom gene turned off is in line with gene regulation concepts.

Answer:

C. Not all cells contain the venom DNA
