DNA/RNA

Front

What are the two molecules that form the sides (backbone) of the DNA ladder?

Back

Deoxyribose sugar and phosphate.

Front

What is the role of helicase in DNA replication?

Back

Helicase is the enzyme that unzips the DNA to prepare for replication.

Front

What DNA base pairs with adenine?

Back

Thymine pairs with adenine.

Front

What is the difference between DNA and RNA in terms of nitrogenous bases?

Back

RNA contains uracil in place of thymine.

Front

If a DNA strand contains 20% thymine, what percentage of guanine is present?

Back

30% guanine.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands that wind around each other.

Front

What are the four nitrogenous bases in DNA?

Back

Adenine, thymine, cytosine, and guanine.

Front

What is the function of DNA polymerase?

Back

DNA polymerase is the enzyme that synthesizes new DNA strands during replication.

Front

What is the primary function of RNA?

Back

RNA serves as a messenger carrying instructions from DNA for controlling the synthesis of proteins.

Front

What is the difference between DNA and RNA in terms of sugar?

Back

DNA contains deoxyribose sugar, while RNA contains ribose sugar.
