Question

Replication of DNA is:

Options

• semiconservative

• requires the unwinding of the double helix.

• involves new complementary nucleotides forming base pairs and then joining to form new strands.

• all of the above.

Answer 1

all of the above.

Explanation:

DNA replication is a multi-step process that involves all these key features. It is called semiconservative because each new DNA molecule keeps one original strand and one new strand. To start this process, the double helix must first unwind and unzip to expose the genetic code. Finally, free complementary nucleotides move in to pair with the exposed bases and are joined together to build the new matching strands.
