After the students identified the correct model, they did additional research on how DNA is replicated. The students then returned to the models that they drew and made the following claims. Student 1: The model does not need to be changed because DNA replication can occur without proteins. Student 2: Proteins need to be added to the model. Without proteins, DNA replication would not be possible. Which of the following statements indicates the correct student claim and provides the appropriate reasoning? Student 1's claim is correct because DNA replicates when nucleotides mix together in the cytoplasm to build a new strand of DNA. Student 1's claim is correct because enzymes unzip the DNA helix so that nucleotides can build a new strand of DNA. C Student 2's claim is correct because proteins separate the two DNA strands and build a new strand of DNA D Student 2's claim is correct because enzymes break down the nuclear envelope so that chromosomes can condense into chromatids.

Transcribed Image Text:Question 10 D
Two students are having a debate in class about how DNA is replicated in the cell. They each draw a model to show how they think DNA is replicated. The figure shows the models
created by Student 1 and Student 2.
