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. |
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 |
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 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. |
