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.

Why do we have so much dna?
jasenka [17]

Answer:

Of the trillions of cells that compose our body, from neurons that relay signals throughout the brain to immune cells that help defend our bodies from constant external assault, almost every one contains the same 3 billion DNA base pairs that make up the human genome – the entirety of our genetic material. It is remarkable that each of the over 200 cell types in the body interprets this identical information very differently in order to perform the functions necessary to keep us alive. This demonstrates that we need to look beyond the sequence of DNA itself in order to understand how an organism and its cells function.
