Question

Part 1 of 3.

You have an ordinary linear ds DNA molecule. Assume the top strand is written in the usual convention for DNA. Suppose the DNA is replicated, using a single origin in the middle of the molecule, and the replication is bidirectional.

Consider a new DNA chain that is made continuously from the origin using the bottom strand as template.

You would find such a strand _______ of the origin.

on the right

on the left

on both sides

on neither side

Part 2 of 3

You have an ordinary linear ds DNA molecule. Assume the top strand is written in the usual convention for DNA. Suppose the DNA is replicated, using a single origin in the middle of the molecule, and the replication is bidirectional.

Consider a new DNA chain that is made continuously from the origin using the bottom strand as template.

The chain should grow __________

left to right.

right to left

both ways

You cannot predict.
