Review DNA Structure and Function Concepts

Front

What holds the two strands of DNA together?

Back

Hydrogen bonds hold the two strands of DNA together.

Front

What are the components of a DNA and RNA nucleotide?

Back

A DNA and RNA nucleotide is made of sugar, phosphate, and a nitrogen base.

Front

Why is the sequence of nitrogen bases in DNA important?

Back

The sequence of nitrogen bases determines the traits that an organism will possess.

Front

What is the function of the sugar-phosphate backbone in DNA?

Back

The sugar-phosphate backbone provides structural support to the DNA molecule.

Front

What makes a model of DNA accurate?

Back

A model of DNA is accurate if it contains correctly paired bases.

Front

What are the four nitrogen bases found in DNA?

Back

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

Front

What is the role of DNA in living organisms?

Back

DNA encodes genetic information necessary for the growth, development, and functioning of living organisms.

Front

How do covalent bonds differ from hydrogen bonds in DNA?

Back

Covalent bonds connect the sugar and phosphate in the backbone, while hydrogen bonds connect the nitrogen bases.

Front

What is the structure of DNA?

Back

DNA has a double helix structure formed by two strands twisted around each other.

Front

What is the significance of complementary base pairing in DNA?

Back

Complementary base pairing ensures accurate replication and transcription of genetic information.
