U5 DNA Structure

Front

How many strands are in DNA?

Back

DNA consists of two strands that form a double helix.

Front

Which monomers are repeatedly joined together to form a strand of DNA?

Back

Nucleotides are the monomers that make up DNA strands.

Front

Guanine bonds with which nitrogenous base?

Back

Guanine bonds with Cytosine.

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of DNA, consisting of a sugar, a phosphate group, and a nitrogenous 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 is the structure of DNA?

Back

DNA has a double helix structure formed by two strands of nucleotides.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are Adenine, Thymine, Cytosine, and Guanine.

Front

What base pairs with Adenine in DNA?

Back

Thymine pairs with Adenine in DNA.

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

What is the difference between DNA and RNA?

Back

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