<h2>
Meselson and Stahl conducted an experiment to determine the correct proposed methods of DNA replication was semi-conservative
. the three proposed models for DNA replication are semi-conservative, conservative, and dispersive.</h2>
Explanation:
In Semi-conservative replication model, the two strands of DNA uncoil from each other. It perform with the original strand and a new strand.
In Conservative replication model, DNA replication didn't open at all, but the parent strands remains undamaged by creating a new and separate molecule that consists of two new strands.
In Dispersive replication model, DNA replication results in two DNA molecules that consists of both parental and daughter DNA.
He demonstrated that semi-conservative DNA replication is an universal mechanism allocated by all organisms on Earth.
The type of inversion is Paracentric inversion.
There are two types of inversion at the chromosome level, depending on the centromere:
Paracentric inversions:
the centromere is not included in the inversion.
Pericentric inversions:
The centromere is included in the inversion which can transform a metacentric chromosome into an acrocentric chromosome.
the structure that will form during synapsis is inversion loop.
These inversions are balanced rearrangements but at the moment of meiosis they cause difficulties in pairing. There is most often formation of a pairing loop. The occurrence of recombination in the inverted segment causes the formation of abnormal gametes by duplication / impairment.
DNA provides information at the species level.
