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.
Answer: Option C
Explanation:
The kingdom Protist and kingdom Fungi has some members that reproduce asexually. Asexual mode of reproduction can be defined as the process by which formation of zygote takes place without the involvement of male and female gametes.
The amoeba and paramecium divides by binary fission and the new individuals formed are identical to their parents.
Some species of fungi also reproduce asexually. Example: zoospores
A point mutation or substitution is a genetic mutation where a single nucleotide base is changed, inserted or deleted from a sequence of DNA or RNA. Point mutations have a variety of effects on the downstream protein product—consequences that are moderately predictable based upon the specifics of the mutation.
