DNA Structure

Front

What is the structure of a DNA molecule?

Back

A DNA molecule is best described as a double helix.

Front

What happens to DNA after replication?

Back

After replication, there are two identical DNA molecules.

Front

Which base is not found in RNA?

Back

The base that does not exist in RNA is Thymine (T).

Front

What amino acid corresponds to the codon GAU?

Back

The amino acid that matches the codon GAU is Aspartic acid (ASP).

Front

How is the DNA sequence GCTATA transcribed to mRNA?

Back

The DNA sequence GCTATA is transcribed to mRNA as CGAUAU.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid.
