DNA Replication Quiz

Kai, Abigail, and Hannah are working on a school project about cell biology. They are specifically interested in where DNA replication occurs in eukaryotic cells. Can you help them?

• In the cytoplasm of the cell

• On the cell membrane

• In the nucleus of the cell

• In the mitochondria of the cell

Evelyn, Mia, and James are studying for their biology exam. They are discussing when DNA replication occurs in eukaryotic cells. Evelyn thinks it's during cytokinesis, Mia thinks it's during meiosis, and James thinks it's during interphase. Who is correct?

• Evelyn (During cytokinesis)

• Mia (During meiosis)

• James (During interphase)

• None of them

Aiden, Samuel, and Lily are studying for their biology exam. They come across a question about DNA replication. They want to know which enzyme is responsible for unwinding the DNA strands during this process. Can you help them?

• DNA Polymerase

• Primase

• Ligase

• Helicase

What is the function of primase in DNA replication?

• Unzipping the DNA strands

• Building new DNA strands

• Adding RNA primers

• Gluing DNA fragments together

Which enzyme is responsible for building new DNA strands during replication?

• Helicase

• Primase

• DNA Polymerase

• Ligase

Aria, Abigail, and Samuel are studying the process of DNA replication in their biology class. They learned that DNA replication proceeds in a specific direction. Can you tell them in which direction does DNA replication occur?

• From North to South, like a compass

• In a clockwise direction, like a clock

• From 3' end to 5' end, like reading a book from back to front

• From 5' end to 3' end, like reading a book from front to back

Ethan, Nora, and Maya are studying DNA replication for their biology exam. Nora explains that one of the strands is built in a specific direction. Ethan asks, 'Which strand is that, Nora?' What is Nora's correct response?

• 'It's the strand with RNA primers.'

• 'It's the strand built in the 5' to 3' direction.'

• 'It's the strand with DNA fragments.'

• 'It's the strand built in the 3' to 5' direction.'

What are the fragments formed on the lagging strand during DNA replication called?

• Primer fragments

• Polymerase fragments

• Ligase fragments

• Okazaki fragments

During a biology class experiment, Hannah, Michael, and Olivia were studying DNA replication. They noticed a particular enzyme that was responsible for joining the DNA fragments together. This enzyme, known as ligase, was (a)   .

• adding RNA primers
• building new DNA strands
• gluing DNA fragments together
• unzipping the DNA strands

Benjamin and Evelyn are studying biology together. They come across a concept where each new DNA double helix formed during replication contains one old strand and one newly made strand. What is the term used to describe this type of DNA replication?

• Dispersive replication

• Semi-conservative replication

• Conservative replication

• Non-conservative replication
