Answer:
The correct answer is "exchange of genetic information between parental chromosomes".
Explanation:
Homologous recombination is a genetic recombination that occurs when two similar or identical molecules of DNA exchange some of its nucleotide sequences. This type of recombination is most widely used for DNA repair purposes, however this is not distinctive of eukaryotes as prokaryotes use it as well. Therefore the most significant an unique role of homologous recombination in eukaryotes is the exchange of genetic information between parental chromosomes. This particular function is known as chromosomal crossover and it is only found in eukaryotes.
<u>Answer</u>:
Potassium inside the cell and sodium out of the cell
<u>Explanation</u>:
The presence of the pump can be seen in plasma membrane of the animal cell. Which can be followed by the ATP, this pump pushes sodium and potassium in completely opposite direction that can be said as against the concentration gradient. In one cycle of this pump, two potassium are ingested inside the cell and three sodium are taken out from the cell. Due to more number of negatively charged proteins inside the cell, potassium ion contains more positive charge so pushed inside the cell. The potassium is pumped through the channels.
