Section: 11.04 Molecular Mechanism of DNA Replication Topic: DNA Replication
Question 33 2.22 / 2.22 pts Bacteria are grown in 15 N (heavy) medium and then transferred to 14 N (light) medium and are allowed to replicate for 1 generation. The DNA is subsequently isolated and centrifuged in a CsCl 2 gradient to yield what type of gradient band(s)? one heavy band one light band one half-heavy (intermediate to heavy and light) band one heavy and one half-heavy band one heavy and one light band Bacteria are grown in 15N (heavy) medium an...
