Question

Because the original strand of the double-stranded helix is found in each daughter cell, the replication process is called:

Options

• proofreading

• semiconservative

• freeing of DNA

• mutation positive

Answer 1

semiconservative

Explanation:

DNA replication is known as semiconservative because each of the two resulting DNA molecules consists of one original (parental) strand and one newly synthesised strand. During this process, the parent double helix unwinds and separates, with every single strand serving as a template for the formation of its new complementary partner. As a result, half of the original genetic material is “conserved” in every new daughter molecule, ensuring that biological information is accurately passed on to each daughter cell.
