DNA replication is called because the newly replicated DNA consist of a parental strand (from the original DNA) and a newly synthesized daughter strand.

Semi-conservative

Explanation:

The semi-conservative DNA replication model was initially hypothesized by Watson and Crick, but was later proven by the Meselson-Stahl experiment, in which DNA samples were tagged, and after replication, it was observed that the two resulting DNA both had one strand each from the parent DNA strand.

This dispelled the conservative model which proposed that the two strands of the daughter DNA are newly synthesized, while the parent DNA only served as a template.

The correct answer is semi-conservative.

SEMI-CONSERVATIVE.

DNA replication is called semi-conservative because the newly replicated DNA consist of a parental strand (from the original DNA) and a newly synthesized daughter strand.

Explanation:

The is so because during DNA replication;

There is the unzipping of the double helix structure of the DNA by an enzyme HELICASE thereby creating replication fork which is Y shaped.

The separated strands each wilk act as templates for making new strands of DNA.

One of the strand is called leading strand oriented in the 3' to 5' direction that is towards the replication fork and the other lagging strand in the 5' to 3' direction.

RNA primase acts on the leading strand acting as the starting point for the synthesis of the new DNA.

DNA polymerase binds to the leading strand and add new complementary necleotides in the 5' to 3' direction.

Okazaki fragments are added to the lagging strand in the 5' to 3' direction. Enzyme ligase seals the DNA strands after proofreading and completes the process of replication.

In conclusion, new DNA strands with half of the parent strand and a half of a newly produced DNA and it's is therefore called Semi- Conservative.
