Front

What are the monomers that make up DNA?

Back

Nucleotides are the monomers that are repeatedly joined together to form a strand of DNA.

Front

What is the sugar component of a nucleotide?

Back

Deoxyribose sugar is the sugar component of a nucleotide.

Front

What is a nucleotide?

Back

A nucleotide is a basic building block of DNA, consisting of a sugar, a phosphate group, and a nitrogen base.

Front

What are the three components of a nucleotide?

Back

The three components of a nucleotide are sugar, phosphate, and nitrogen base.

Front

What type of bond joins the nitrogenous bases in DNA?

Back

Hydrogen bonds join the two strands of nitrogenous bases in DNA.

Front

What are the four nitrogen bases found in DNA?

Back

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

Front

What is the role of the phosphate group in a nucleotide?

Back

The phosphate group links the sugar of one nucleotide to the sugar of another, forming the backbone of the DNA strand.

Front

How do adenine and thymine pair in DNA?

Back

Adenine pairs with thymine through two hydrogen bonds.

Front

How do cytosine and guanine pair in DNA?

Back

Cytosine pairs with guanine through three hydrogen bonds.

Front

What is the structure of DNA?

Back

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