<h3>What are isotopes?</h3>

Isotopes are atoms of the same element which have different numbers of neutrons but the number of protons and electrons remains same.

As the isotopes of the atom have the same number of protons, so, their atomic number will also be the same.

Thus, it can be concluded that atoms of isotopes of the same element contain the same number of protons.

photoshop1234 [79]

Answer: Replication is called semiconservative because each of the original strand is is used as a template for the synthesis of a new strand

Explanation: DNA is a double-stranded helix containing two antiparallel strands that are complementary to each other.

Replication is the process of making identical copies of a DNA molecule. Before replication begins, the double-stranded DNA is first unwound by helicase so that each strand will serve as a template for new strand synthesis.

DNA replication is semiconservative because each DNA strand serves as a template for the synthesis of a new strand, producing two new DNA molecules each one with one new strand and one strand.

Saved and used in the new strand
