Suppose the Experiment of Meselson and Stahl Was Performed on a Sample

Multiple Choice

Suppose the experiment of Meselson and Stahl was performed on a sample of 8 cells, each containing one copy of its circular double-stranded DNA genome, and that had been growing on normal ¹⁴N medium.You then grew the cells for 3 generations in medium containing ¹⁵N.The outcome would be

A) 8 cells with single-stranded DNA molecules with ¹⁴N, and 24 cells with single-stranded DNA molecules with ¹⁵N.
B) 16 cells with double-stranded DNA molecules with equal amounts of ¹⁴N and ¹⁵N, and 48 cells with double-stranded DNA molecules with ¹⁵N.
C) 8 cells with double-stranded DNA molecules with equal amounts of ¹⁴N and ¹⁵N, and 24 cells with double-stranded DNA molecules with ¹⁵N.
D) 8 cells with double-stranded DNA molecules with equal amounts of ¹⁴N and ¹⁵N, and 32 cells with double-stranded DNA molecules with ¹⁵N.
E) 65 cells with single-stranded DNA molecules with ¹⁵N.
