This activity contains 5 questions.
Which of the following build(s) new strands of DNA?
The lagging strand
The origins of replication
The leading strand
Which statement about DNA replication is CORRECT?
The leading strand is one of the strands of parental DNA.
The lagging strand is one of the strands of parental DNA.
The leading strand is built continuously, and the lagging strand is built in pieces.
DNA ligase helps assemble the leading strand.
The lagging strand is built continuously.
During DNA replication, which nucleotide will bind to an A nucleotide in the parental DNA?
The molecule that seals the gaps between the pieces of DNA in the lagging strand is
the replication fork.
the leading strand.
Which statement about DNA replication is FALSE?
Because the two strands of parental DNA run in opposite directions, the new strands must be made in different ways.
DNA ligase adds nucleotides to the lagging strand.
The two strands of parental DNA are separated during DNA replication.
The lagging strand is made of a series of pieces that must be joined together to make a continuous strand.
DNA polymerase builds a new strand by adding DNA nucleotides one at a time.
