During dna transposition by the cut-and-paste mechanism, the transposase cuts the two strands of the target site dna several nucleotides apart. cellular repair enzymes fill in these overhangs, resulting in the formation

Long terminal repeats.

Explanation:

Transposable element may be defined as the DNA sequence that can move from one place to the other place in the genome. These are also known as jumping genes.

These gene can move through the cut - paste mechanism and copy-paste mechanism. The gene consist of the transposase enzyme that cuts the DNA strand. The gaps are filed by the repair enzymes. This involves in the formation of the long terminal repeats at the DNA sequence.

Thus, the correct answer is long terminal repeats.

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
