Question

Why is it important for DNA to unwind before replication?

Responses

to expose bases so they can be paired with new bases


to improve flexibility in the DNA strand's phosphate backbone


to allow proteins to check for mistakes in the DNA strands


to prevent the new DNA from accidentally sticking together

Answer 1

All

Step-by-step explanation:

All of the responses in the selection are related to the importance of DNA unwinding before replication:

"To expose bases so they can be paired with new bases"

"To improve flexibility in the DNA strand's phosphate backbone"

"To allow proteins to check for mistakes in the DNA strands"

"To prevent the new DNA from accidentally sticking together"

Each of these factors plays a role in the overall process of DNA replication, and together they help ensure that the process occurs efficiently and accurately.
