DNA Replication

Front

What is the role of helicase in DNA replication?

Back

Helicase is the enzyme that unzips the DNA double helix, separating the two strands to prepare for replication.

Front

Which base does adenine pair with in DNA?

Back

Adenine pairs with thymine.

Front

What is the outcome of DNA replication?

Back

DNA replication results in two DNA molecules, each consisting of one original strand and one newly synthesized strand.

Front

In a DNA strand, if one strand is AGC, what would be the complementary strand?

Back

The complementary strand would be TCG.

Front

What is the complementary DNA strand for AATCATGGA?

Back

The complementary strand is TTAGTACCT.

Front

What is the function of DNA polymerase?

Back

DNA polymerase is the enzyme responsible for synthesizing new DNA strands by adding nucleotides complementary to the template strand.

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, thymine, cytosine, and guanine.

Front

What is the significance of the 5' and 3' ends of a DNA strand?

Back

The 5' and 3' ends indicate the directionality of the DNA strand, which is important for replication and transcription.

Front

What is semi-conservative replication?

Back

Semi-conservative replication is the process by which each new DNA molecule consists of one original strand and one newly synthesized strand.
