DNA Structure and Replication

Front

Why is DNA important?

Back

It serves as the blueprint for making proteins in living organisms.

Front

Describe the 2 DNA molecules produced during DNA replication.

Back

Each molecule has an original side and a new side.

Front

Which shows the correct complementary nitrogen base pairing for DNA?

Back

T-A, G-C.

Front

Guanine bonds with ______________.

Back

Cytosine.

Front

What is the first step in the process of DNA replication?

Back

Enzymes 'unzip' the DNA molecule by breaking the hydrogen bonds.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides.

Front

What are the building blocks of DNA?

Back

Nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

Name the four nitrogenous bases in DNA.

Back

Adenine, Thymine, Cytosine, Guanine.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase adds nucleotides to the growing DNA strand during replication.

Front

What is semi-conservative replication?

Back

It is the process where each new DNA molecule consists of one original strand and one new strand.
