are enzyme used during replication to attach okazaki fragments to each other.

DNA ligase

Explanation:

After Okazaki fragments (sequences complementary to the lagging strand of DNA) are produced, they must be joined together to produce a continuous strand. The Okazaki fragments are then joined up by DNA ligase, which catalyzes the formation of a phosphodiester bond between the neighboring nucleotides.

for example, no new evidence will demonstrate that the earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the earth is not divided into solid plates that have moved over geological timescales .
