Isabel Objective 12

Name the monomer/building block of DNA shown below.

Identify the 3 parts that make it up.

Identify the complementary nitrogenous base to Cytosine.

Put the steps of DNA replication in order.

1. DNA helicase unzips DNA
2. DNA polymerase adds complementary base pairs to each original strand
3. Two new identical strands of DNA are formed, each with one new strand and one old strand.

Structural components of our body always match the function of the part. For DNA, its structure helps its function greatly. Which of the following makes it easy for DNA to unzip during DNA replication?
