DNA Structure and Replication

Front

What are the 4 nitrogenous bases in DNA?

Back

Adenine, Thymine, Cytosine, and Guanine.

Front

A monomer of DNA is called a(n)

Back

Nucleotide.

Front

I am made of nucleotides.

Back

Both DNA and RNA.

Front

What is the correct order of steps for DNA replication?

Back

Unwind, unzip, bring in new nucleotides, wind back up.

Front

Which of the following best describes a DNA molecule?

Back

Double helix.

Front

What is the structure of DNA?

Back

DNA is structured as a double helix, consisting of two strands that wind around each other.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the function of the nitrogenous bases in DNA?

Back

Nitrogenous bases pair with each other (A with T, C with G) to form the genetic code.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and is double-stranded, while RNA contains ribose sugar and is usually single-stranded.

Front

What is the significance of the 5' and 3' ends of a DNA strand?

Back

The 5' end has a phosphate group, and the 3' end has a hydroxyl group, determining the direction of DNA synthesis.
