DNA Replication

Which protein joins together the Okazaki fragments of DNA in the lagging strand?

DNA ligase DNA ligase joins the Okazaki fragments in the lagging strand, turning it into a continuous strand.

Which statement about DNA replication is FALSE?

DNA ligase adds nucleotides to the lagging strand. This statement is FALSE. DNA ligase joins the Okazaki fragments in the lagging strand, turning it into a continuous strand. It does not add nucleotides to the lagging strand.

Which of the following builds new strands of DNA?

DNA polymerase is an enzyme that builds new strands of DNA. It does this by adding DNA nucleotides one at a time.

During DNA replication, which nucleotide will bind to an A nucleotide in the original or parental DNA strand?

T During DNA replication, A only binds with T and T only binds with A

Which statement best describes strand characteristics as it relates to DNA replication?

The leading strand is built continuously, and the lagging strand is built in pieces. This statement is correct! Because strands in a DNA double helix run in opposite directions, the new strands must be made in different ways. The leading strand is built continuously
