DNA and DNA Replication

Front

What are the components of the backbone of a DNA molecule?

Back

The backbone of a DNA molecule is made from a 5 carbon sugar (deoxyribose) and a phosphate group.

Front

What type of sugar is found in DNA?

Back

The sugar in DNA is deoxyribose.

Front

What is the process called when DNA makes a copy of itself?

Back

The process is called DNA replication.

Front

What enzyme is responsible for building new DNA strands during replication?

Back

The enzyme responsible for building new DNA strands during replication is DNA polymerase.

Front

What are the two main functions of DNA?

Back

The two main functions of DNA are to store genetic information and to provide instructions for protein synthesis.

Front

What is the structure of DNA?

Back

DNA has a double helix structure, consisting of two strands that wind around each other.

Front

What are the four nitrogenous bases 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).

Front

What role does helicase play in DNA replication?

Back

Helicase unwinds the DNA double helix, separating the two strands to allow replication.

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 strand, which is important for replication and transcription.
