Front

What is the structure of a DNA molecule?

Back

A DNA molecule is best described as a double helix.

Front

What are the components of a nucleotide?

Back

Nucleotides are made of sugar, phosphate, and a nitrogen base.

Front

In which organelle is DNA usually found?

Back

DNA is usually found in the nucleus.

Front

What are the four nitrogen bases in DNA?

Back

The four nitrogen bases in DNA are adenine, thymine, cytosine, and guanine.

Front

What is a gene?

Back

A gene is a section of DNA that codes for a specific protein.

Front

What is the role of the sugar in a nucleotide?

Back

The sugar in a nucleotide helps form the backbone of the DNA structure.

Front

What is the function of the phosphate group in DNA?

Back

The phosphate group links the sugar molecules together, forming the DNA backbone.

Front

How do adenine and thymine pair in DNA?

Back

Adenine pairs with thymine through hydrogen bonds.

Front

How do cytosine and guanine pair in DNA?

Back

Cytosine pairs with guanine through hydrogen bonds.

Front

What is the significance of the double helix structure of DNA?

Back

The double helix structure allows DNA to be stable and compact, facilitating storage and replication.
