Which of the following RNA molecules is responsible for carrying the code that will be read at the ribosome in order to create a protein?

The leading strand is replicated __________, and the lagging strand is replicated __________.

DNA replication is semi-conservative. This means that __________.

The process of DNA replication is considered semiconservative. DNA is created by using another DNA strand as a template, and building a new complementary strand onto the pre-existing strand. Each new DNA molecule contains one strand from the parent template, and one newly synthesized strand.

A single DNA molecule (one double-helix) undergoes three rounds of replication. After the final replication is complete, how many of the DNA molecules present do not contain any part of the original template?

During DNA replication, what purpose does the enzyme primase serve?

DNA polymerase is the protein that adds new nucleotides to the elongating DNA strand during replication. In order for DNA polymerase to bind the template strand and add new nucleotides, a free 3' hydroxyl group must be exposed to accept the first nucleotide.

Which of the following is created to provide a free 3' hydroxyl group, enabling the initiation of DNA replication?

Which DNA polymerase is responsible for exchanging RNA primers for DNA nucleotides during discontinuous replication?

DNA polymerase only functions in the 3'-to-5' direction. This means that it adds nucleotides to a free 3' hydroxyl group. DNA is replicated on both strands simultaneously. Since DNA is anti-parallel (the strands run in opposite directions), one new strand is being created continuously, while the other is being created in fragments.

What is the correct name of the fragments of the lagging strand?

DNA synthesis always occurs in the __________ direction, so one new strand is synthesized continuously towards the replication fork, producing the __________ strand. The other strand, known as the __________ strand, forms away from the replication fork in small fragments.

The enzyme helicase opens the double helix of DNA at points called __________.
