Arrange the events in the order that they occur during DNA replication. Helicase unzips DNA to separate strands.

Polymerase synthesizes
new DNA strands.

Topoisomerase unwinds
the coiled DNA.

The new strands are
glued using ligase.
Primase lays down
short RNA strands.

Americium-241 undergoes fission to produce three neutrons per fission event. if a neutron-absorbing material is mixed in with this sample so that the rate of neutron production drops down to 1.8 neutrons per fission event, which will be effective at achieving a critical mass? check all that apply. remove a deflective shield surrounding the sample. remove absorbent material mixed in with the sample. compress the sample of americium-241.

All of the following are homogeneous mixtures except a) sugar dissolved in water. b) orange juice. c) coffee with cream. d) household vinegar. e) apple juice
