DNA Replication Quiz

What are the three steps of DNA replication?

• initiation, elongation, and termination, and mutation

• initiation, elongation, and termination

• replication, transcription, and translation

• transcription, translation, and mutation

Which enzyme is responsible for DNA replication?

• DNA polymerase

• Helicase

• Ligase

• RNA polymerase

What are Okazaki fragments?

• Fragments of RNA that are synthesized during transcription.

• Short, degraded DNA fragments formed during DNA repair.

• Long, newly synthesized DNA fragments formed on the leading strand during DNA replication.

• Short, newly synthesized DNA fragments formed on the lagging strand during DNA replication.

What is the leading strand in DNA replication?

• The complementary strand

• The leading strand

• The lagging strand

• The template strand

What is the lagging strand in DNA replication?

• The coding strand

• The template strand

• The lagging strand

• The leading strand

During which step of DNA replication are Okazaki fragments formed?

• leading strand synthesis

• lagging strand synthesis

• initiation

• elongation

What is the function of DNA polymerase in DNA replication?

• DNA polymerase repairs damaged DNA during DNA replication.

• DNA polymerase breaks down DNA strands during DNA replication.

• DNA polymerase regulates the speed of DNA replication.

• DNA polymerase synthesizes new DNA strands during DNA replication.

Which strand is synthesized continuously during DNA replication?

• lagging strand

• template strand

• leading strand

• complementary strand

Which strand is synthesized discontinuously during DNA replication?

• leading strand

• continuous strand

• lagging strand
