DNA Replication

Front

What is DNA replication?

Back

DNA replication is the process by which a cell makes an exact copy of its DNA, ensuring that each new cell receives a complete set of genetic information.

Front

What is the shape of DNA?

Back

The shape of DNA is a double helix, which resembles a twisted ladder.

Front

What is the significance of DNA in living organisms?

Back

DNA serves as the blueprint for the traits of all living things, determining characteristics and functions.

Front

What are the two main stages of DNA replication?

Back

The two main stages of DNA replication are unwinding the double helix and synthesizing new strands.

Front

What enzyme is responsible for unwinding the DNA during replication?

Back

The enzyme responsible for unwinding the DNA is called helicase.

Front

What is the role of DNA polymerase in replication?

Back

DNA polymerase is the enzyme that adds new nucleotides to the growing DNA strand during replication.

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 is the difference between leading and lagging strands in 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, known as Okazaki fragments, away from the fork.

Front

What is semi-conservative replication?

Back

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

Front

What are Okazaki fragments?

Back

Okazaki fragments are short segments of DNA synthesized on the lagging strand during DNA replication.
