Question

How many of the following statements about DNA recombination are true? It is a natural process where genetic information is rearranged to form new associations If the recombination involves a reaction between homologous sequences it is called homologous recombination If the recombination involves a reaction between different nucleotide sequences it is called non-homologous recombination the Holliday model is the model showing recombination for non-homologous chromosomes Recombination occurs randomly around a chromosome.

Answer 1

Answer:

All the statements about DNA recombination are true.

Explanation:

Recombination can be defined as any process in which the formation of new DNA from different molecules takes place, so that the genetic information derived from each original DNA molecule will be present in the new ones. Allows random rearrangement of genes within and between chromosomes.

It constitutes a source of genetic variability and physical exchange of segments. It has regulatory value, since it can result in the activation or inactivation of genes and is also a repair pathway.

There is general or homologous recombination, which occurs between substrates with extensive homology.

Site-specific recombination, where there is an exchange of two specific DNA sequences.

And transposition, which involves a short segment of DNA that moves from one place to another on the same or different chromosome.
