DNA Replication

Front

What is the result of DNA replication?

Back

DNA replication results in two DNA molecules, each one with one new strand and one original strand.

Front

What enzyme is responsible for unzipping the DNA during replication?

Back

The enzyme that unzips the DNA to prepare for replication is helicase.

Front

What are the two components that make up the backbone of a DNA nucleotide?

Back

The backbone of a DNA nucleotide is composed of deoxyribose sugar and a phosphate group.

Front

What is the process called in which DNA makes an exact copy of itself?

Back

The process in which DNA has the unique ability to make an exact copy of itself is called replication.

Front

What are the four nitrogen bases found in DNA?

Back

The four nitrogen bases in DNA are adenine, thymine, cytosine, and guanine.

Front

What is the role of DNA polymerase in DNA replication?

Back

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

Front

What is the significance of the antiparallel structure of DNA?

Back

The antiparallel structure of DNA allows for the complementary base pairing and proper functioning of enzymes during replication.

Front

What is the difference between leading and lagging strands during DNA replication?

Back

The leading strand is synthesized continuously in the direction of the replication fork, while the lagging strand is synthesized in short segments (Okazaki fragments) away from the fork.

Front

What is the function of RNA primers in DNA replication?

Back

RNA primers provide a starting point for DNA polymerase to begin synthesis of the new DNA strand.

Front

What is the role of ligase in DNA replication?

Back

Ligase is the enzyme that joins Okazaki fragments on the lagging strand, sealing the gaps between them.
