DNA Structure and Replication

Front

What is the role of DNA Polymerase in DNA replication?

Back

DNA Polymerase is the enzyme that adds nucleotides to the 3' end of a growing DNA strand during replication.

Front

What is a monomer of DNA called?

Back

A monomer of DNA is called a nucleotide.

Front

What function does DNA helicase serve during DNA replication?

Back

DNA helicase unwinds and unzips the DNA double helix, allowing the replication process to occur.

Front

What is the five-carbon sugar found in DNA?

Back

The five-carbon sugar found in DNA is deoxyribose.

Front

Why is it crucial for DNA to be copied accurately?

Back

It is crucial for DNA to be copied accurately to ensure that the new cell receives the correct instructions for functioning.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides, which consist of a phosphate group, a five-carbon sugar, and a nitrogenous base.

Front

What are the four nitrogenous bases found in DNA?

Back

The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

How do the nitrogenous bases pair in DNA?

Back

In DNA, adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G) through hydrogen bonds.

Front

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

Back

The 5' and 3' ends of a DNA strand indicate the directionality of the DNA molecule, which is crucial for replication and transcription.

Front

What is the function of RNA primer in DNA replication?

Back

The RNA primer provides a starting point for DNA polymerase to begin adding nucleotides during DNA replication.
