Semi-conservative hypothesis : verification using chromosome marking ...
- Refers to the fact that after the replication of one DNA helix each of the two daughter helices that result contain one newly-synthesized and one pre- existing strand of DNA.
The term proposed by Delbrück and Stent (1957) to describe the method of replication of DNA postulated by Watson and Crick (1953) in which the molecule divides longitudinally, ...
replication the mechanism by which DNA produces identical copies of itself
Sepal the outermost structures of a flower that makes up the calyx.

the replication of a chromosome is semi-conservative (just as is the replication of a single DNA molecule).
parent DNA molecule separates into its two component strands, each of which acts as a template for the formation of a new complementary strand. The two daughter molecules therefore contain half the parent DNA and half new DNA ( ...
DNA Replication (Semi-Conservative Replication)
Transcription: DNA to mRNA
Translation: mRNA to Protein via tRNA ...
DNA replication is as both of the DNA molecules produced are formed from an old strand and a new one.
Nucleotide triphosphates (in the forms ATP, GTP, CTP and TTP) are assembled according to the semi-conservative model. Other details of DNA replication are consistent with what we know for prokaryotes.

synthesis (S), in which the cell duplicates its DNA (via semi-conservative replication).
This is called "" replication since one of the parent strands is "conserved" in the new DNA molecule.
The bacteria were then transferred to a medium with light (Nitrogen-14) medium. Watson and Crick had predicted that DNA replication was semi-conservative.
