Question

what were the results from chargaffs experiment? select all that apply.
□ a) adenine binds with guanine
□ b) adenine binds with thymine
□ c) thymine binds with guanine
□ d) adenine binds with cytosine
□ e) cytosine binds with guanine
□ f) cytosine binds with thymine

Explanation:

Chargaff's rules state that in DNA, the amount of adenine (A) is equal to thymine (T), and the amount of cytosine (C) is equal to guanine (G). This implies that adenine binds with thymine, and cytosine binds with guanine. So we check each option:

• Option A: Adenine does not bind with guanine (A pairs with T), so A is incorrect.
• Option B: Adenine binds with thymine (consistent with Chargaff's rules), so B is correct.
• Option C: Thymine does not bind with guanine (T pairs with A), so C is incorrect.
• Option D: Adenine does not bind with cytosine (A pairs with T), so D is incorrect.
• Option E: Cytosine binds with guanine (consistent with Chargaff's rules), so E is correct.
• Option F: Cytosine does not bind with thymine (C pairs with G), so F is incorrect.

Answer:

B. adenine binds with thymine, E. cytosine binds with guanine
