because one original strand of the double-stranded helix is found in each daughter molecule, the replication process is called
Finger [1]

Because one original strand of the double-stranded helix is ​​found in each daughter molecule, the replication process is called semiconservative.

Replication is the process by which a DNA molecule generates two identical to itself, and is key in cell reproduction.

All cells in the body must have the exact same genome (as in asexual reproductive organisms, which are practically clones of each other) and this is achieved through replication.

The process consists of separating the two strands of DNA, each of which will function as a template to synthesize a new one.

That is, each of the two strands of DNA serves as a template to synthesize a new complementary strand of the template.

In the end, two DNA molecules are formed, each of the two DNA molecules has a new chain and one original strand, this mode of replication is called semi-conservative.

Therefore, we can conclude that because one original strand of the double-stranded helix is ​​found in each daughter molecule, the replication process is called semiconservative.
