Question

how does the substitution of arsenic for phosphorus in dna impact/ effect the stability and functionality of the molecule? (bacteria article)
arsenic cannot bond with oxygen effectively, limiting dnas ability to support life.
all of the above
arsenic forms weaker bonds compared to phosphorus, making the dna less stable.
arsenic forms the same types of bonds, making no difference in dna structure.

Explanation:

• Arsenic cannot bond with oxygen effectively, which limits DNA's ability to support life.
• Arsenic forms weaker bonds compared to phosphorus, making the DNA less stable.
• Since both of the above statements are correct, the answer is "All of the above".

Answer:

B. All of the above
