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

What two molecules form the backbone of the DNA ladder?

Back

The backbone of the DNA ladder is formed by deoxyribose sugar and phosphate.

Front

In which organelle is DNA usually found?

Back

DNA is usually found in the nucleus of the cell.

Front

What type of bond joins nitrogenous bases in DNA?

Back

Nitrogenous bases in DNA are joined by hydrogen bonds.

Front

What is the order of DNA replication?

Back

The order of replication is 3, 4, 1, 2.

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 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 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 crucial 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.

Front

What is the function of ligase in DNA replication?

Back

Ligase is the enzyme that joins Okazaki fragments on the lagging strand during DNA replication.
