DNA Structure (PLTW 1.1.5)

Front

What is the structure of a DNA molecule?

Back

A DNA molecule is structured as a double helix.

Front

Which nitrogen base does Cytosine pair with?

Back

Cytosine always pairs with Guanine.

Front

What is the primary function of DNA?

Back

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

Front

What accounts for differences in traits between siblings?

Back

Differences in traits are due to variations in the sequence of nitrogen bases in their DNA.

Front

According to Chargaff's rule, which base pairs with Cytosine?

Back

Cytosine pairs with Guanine.

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 Thymine in DNA?

Back

Thymine pairs with Adenine in the DNA structure.

Front

How does DNA replicate?

Back

DNA replicates by unwinding and separating into two strands, each serving as a template for a new complementary strand.

Front

What is a nucleotide?

Back

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

Front

What is the significance of the sequence of nitrogen bases in DNA?

Back

The sequence of nitrogen bases determines the genetic information and traits of an organism.
