DNA Replication

Front

What is DNA replication?

Back

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 role of DNA Helicase in DNA replication?

Back

DNA Helicase unwinds the original DNA strand, separating the two strands to allow replication to occur.

Front

What is the function of RNA Primase?

Back

RNA Primase lays down an RNA primer that provides a starting point for DNA polymerase to begin adding new nucleotide bases.

Front

What does DNA Polymerase do during replication?

Back

DNA Polymerase builds new strands of DNA by adding complementary nucleotide bases to the template strand.

Front

What is the role of DNA Ligase?

Back

DNA Ligase joins together Okazaki fragments on the lagging strand, sealing gaps between newly synthesized DNA segments.

Front

What are Okazaki fragments?

Back

Short segments of DNA synthesized on the lagging strand during DNA replication, which are later joined by DNA Ligase.

Front

What is the base pairing rule in DNA?

Back

Adenine (A) pairs with Thymine (T), and Cytosine (C) pairs with Guanine (G) in the DNA double helix.

Front

What is the significance of the 5' to 3' direction in DNA replication?

Back

DNA strands are synthesized in the 5' to 3' direction, meaning new nucleotides are added to the 3' end of the growing strand.

Front

What is a template strand in DNA replication?

Back

The original strand of DNA that serves as a guide for synthesizing a new complementary strand.

Front

What is the difference between leading and lagging strands?

Back

The leading strand is synthesized continuously in the same direction as the replication fork, while the lagging strand is synthesized in short segments in the opposite direction.
