<em>The replication of the DNA is </em><em>semi conservative.</em><em> This means that newly replicated double helix DNAs usually consist of one parental strands and one newly synthesized strands. The parental DNA unwinds and each strand serves as template for the synthesis of complementary strands.</em>

In the case of XNA, the two strands of parental XNA were found intact, meaning that the newly produced XNA consist of two newly synthesized strands. This thus means that the replication process is conservative.

Hence, unlike DNA replication that is semi conservative, XNA replication is conservative.

Compare and contrast the processes that form different fossil types

<h3><u>Processes that form different fossil types:</u></h3>

The remained parts and elements of an organism that live several years ago is called as fossils.

Due to natural processes like weathering, soil erosion and other geological activities fossils are hard to preserve.

Carbonization, permineralization, recrystallization and replacement are the fossil formation processes.

Carbonization is the chemical reaction forming the thin film of carbon of the organic material.

Permineralization includes the fossils of bones and teeth. The recrystallization process is responsible for changing the micro-structure of the organic materials to form the fossils.
