Expert Solution

Twentieth century experiment provide evidence to support claims about the structure of DNA.

Our modern understanding of DNA's role in heredity has led to a variety of practical applications, including forensic analysis, paternity testing and genetic screening.

The work of additional scientists around the turn of the 20th century, including theodor Bovari, Walter sutton and Thomas hunt morgan, established that mendels heiable fators were most likely carried on chromosomes.

The work of these researchers provided strong evidence for DNA as the genetic matrial.

The replication fork is a structure that forms within the long helical DNA during DNA replication.

Which created by helicases, which break the hydrogen bonds, holding the two DNA stands together in the helix.

The resulting structure has two branching prongs, each one made up of a single strand of DNA.
