Mr T DNA Replication & Structure

Because each strand of DNA can be used to make the other strand, the strands are said to be...

• identical
• complementary
• opposite

Before a cell divides, it duplicates its DNA in what copying process?

• replication
• reproduction
• DNA synthesis

During which phase of the cell cycle is DNA replicated?

• prophase
• interphase
• metaphase
• telophase

During replication, which sequence of nucleotides would bond with the DNA sequence A-T-A-C-G?

• A-T-A-C-G
• G-C-A-T-A
• A-A-T-G-C
• T-A-T-G-C

Which enzyme "unzips" DNA by breaking the bonds between base pairs and unwinding the strands?

• primase
• helicase
• DNA polymerase
• ligase

Each DNA molecule resulting from replication has one original strand and one new strand.

• true
• false

Which enzyme joins individual nucleotides to build and produce a new strand of DNA?

• helicase
• ligase
• DNA polymerase
• telomerase

The parent strand that runs from 3'-5' towards the replication fork is called the...

• leading strand
• lagging strand
• Okazaki fragment strand

What enzyme "glues" together the Okazaki fragments that DNA polymerase is unable to synthesize?

• helicase
• ligase
• telomerase
• primase

In eukaryotes, replication proceeds from multiple starting points on individual chromosomes.

• True
• False
