Answer:

join DNA fragments by the formation of phosphodiester bonds.

Explanation:

DNA ligase is an enzyme which has the role to join fragments of DNA after they are being cleaved with endonucleases. This enzyme is also important in DNA replication, because it links the ends after the excision of primer in lagging DNA strand.

DNA ligase is also used in the cloning of DNA: vector DNA and foreign DNA contain compatible ends(after treatment with the same restriction enzymes) that can be joined together by molecular ligation via DNA ligase enzyme.

When the freeze occur it expands the rock and when the temperature increases above freezing the thaw ice further penetrate into the crack.

Weathering the breaking down of rock into smaller frequent affects freeze-thaw as it allows water to penetrate into cracks.

Slump is the downward movement of materials from rock surface, it allows material to move alone the rock surface liquid such as water can be allowed to move and penetrate cracks. crack rock fragment that results from freeze thawing are deposited at rock base and form smaller rocks

Creep is also the movements of weathered materials down the slope of rock surfaces. It could result from freeze thaw.
