Which of the following statements about transposable genetic elements is NOT true?
Katarina [22]

Answer:

C. They all use a cut and paste mechanism.

Explanation:

DNA transposons can go through a replicative or nonreplicative transposition.

The replicative transposition uses a "copy and paste" mechanism that consists of the introduction of a new copy of the transposable element in a new position, meanwhile <u>the old copy remains in the original position</u>. This determines an increase in the number of copies.

The nonreplicative transposition uses a "cut and paste" mechanism that consists of the cleavage of the transposable element from its position and its <u>insertion in a new position</u> without increasing the number of copies.

Retrotransposons, on the other side, move through RNA intermediates generated by the reverse transcriptase.

Nata [24]

The type of cell division observed in the Figure is Meiosis. It can be deciphered by the presence of recombination between homo-logous chromosomes.

<h3>What is Meiosis?</h3>

Meiosis is a type of reductional cell division by which a cell produces four daughter cells having half of the genetic material.

Meiosis is a cell division that involves a genetic phenomenon known as recombination or crossing over.

Recombination refers to the exchange of genetic material between non-sister chromatids during Prophase I.
