DNA Replication

Front

What is the base pairing rule in DNA?

Back

In a molecule of double-stranded DNA, Adenine (A) pairs with Thymine (T), and Cytosine (C) pairs with Guanine (G).

Front

What are the two main components of the DNA backbone?

Back

The two molecules that form the sides (backbone) of the DNA ladder are deoxyribose sugar and phosphate.

Front

What is the complementary DNA strand for the sequence ATG TGA CAG?

Back

The complementary DNA strand is TAC ACT GTC.

Front

What is the role of DNA polymerase in DNA replication?

Back

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

Front

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

Back

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

Front

What is the process of DNA replication?

Back

DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules.

Front

What is the function of helicase in DNA replication?

Back

Helicase is an enzyme that unwinds and separates the double-stranded DNA during replication.

Front

What are Okazaki fragments?

Back

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

Front

What is the difference between the leading strand and the lagging strand in DNA replication?

Back

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

Front

What is the role of ligase in DNA replication?

Back

DNA ligase is an enzyme that joins Okazaki fragments together on the lagging strand to create a continuous DNA strand.
