DNA Structure

Front

What are the four DNA bases?

Back

Adenine (A), Thymine (T), Cytosine (C), Guanine (G)

Front

Which base is not found in DNA?

Back

Histidine (H) is not a DNA base.

Front

What is the result of DNA replication?

Back

At the end of replication, there are 2 DNA molecules.

Front

What do the two strands of DNA consist of after replication?

Back

Each DNA molecule consists of one original strand and one new strand.

Front

What accounts for differences in traits between siblings?

Back

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

Front

What is the common feature of all organisms?

Back

All organisms have DNA sequences made of A, C, T, and G.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides.

Front

What are nucleotides made of?

Back

Nucleotides are made of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the role of DNA in cells?

Back

DNA stores genetic information and provides instructions for protein synthesis.

Front

What is complementary base pairing?

Back

In DNA, adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G).
