Why is it called Semi-conservative replication when DNA molecules duplicate themselves?

If the two complementary strands of a double helix seperated, by breaking the hydrogen bonds of each base pair, each parental strand could direct the synthesis of a new complementary strand because of the specific base-pairing requirments.That is, each parental strand could function as template, a single strand of DNA that specifies the nucleotide sequence of a new complemetary strand. This mechanism of DNA replication is called " semiconservative Replication" because each of the complementary strand of the parent double helix is conserved during this process.

The question is what happens to the original strand of DNA when it replicates? In semi-conservative replication, the original splits in half (into two strands) and each strand forms the basis for a new molecule, both of which are identical to the original chemically, but only contain half of the atoms from the original molecule. One new strand, one old strand.

DNA is basically made up two strands, each of which acts as a platform for the new strand to form on it by advent of complementary base pair on them by the DNA polymerases. thus on the whole out of the the 2 new daughter dna helixes one strand in each is the parent strand and the other the newly synthesized daughter strand. therefore 50% of the 2nd generation is quantitatively the parent generation.

because the new strand of DNA is not compleately new. Half of it is from the orgiinal strand. You start of with one double stranded DNA molecule and you end up with 2 double stranded DNA molecules. Each new one has one strand from the original strand.

interior sight individuals are actually not East Asians in any respect. there's an inclination between Eurocentric pupils in line with superficial likeness to assimilate interior sight individuals with East Asians. they have an particularly diverse DNA. Eurocentric pupils try this lots; perhaps they want to teach that interior sight individuals are actually not so "interior sight" in spite of everything and that they are descendants of East Asians who crossed the Bering Strait hundreds of years in the past. a similar Eurocentric pupils do not do a similar element with Melanesians, papuans or maybe the Olmecs (who seem to have "African effective properties"). They by no skill ask regardless of if Melanesians, papuans or maybe Olmecs are African in line with their effective properties. Equating interior sight individuals with East Asians proves that Eurocentric pupils and people who've been brainwashed via them have a racist time table.
