DNA Structure

Front

The structure of our DNA can be described as

Back

a double helix

Front

The basic building blocks of DNA are

Back

nucleotides

Front

Why is DNA important?

Back

It serves as the blueprint for traits of all living things.

Front

Which 2 molecules form the sides (backbone) of the DNA ladder?

Back

deoxyribose (sugar) and phosphate

Front

Which of the following is a base pair?

Back

Cytosine - Guanine

Front

What are the four nitrogenous bases in DNA?

Back

Adenine, Thymine, Cytosine, Guanine

Front

What is the role of deoxyribose in DNA?

Back

Deoxyribose is the sugar that forms part of the DNA backbone.

Front

What is the function of the phosphate group in DNA?

Back

The phosphate group links the deoxyribose sugars together, forming the DNA backbone.

Front

What is complementary base pairing?

Back

It is the specific pairing of nitrogenous bases: Adenine with Thymine, and Cytosine with Guanine.

Front

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

Back

It allows DNA to be compact and stable while also enabling replication and transcription.
