Luden [163]

Answer:

The correct answer is "exchange of genetic information between parental chromosomes".

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.

Answer:

A . proteins can take a variety of shapes, and nucleic acids tend to form linear chains

Explanation:

Proteins are consist of 50 and 2000 amino acid long and can take variety of shapes in living organisms. Two types of proteins that found in living cells are globular proteins and fibrous proteins and they have different shapes. Example of  globular protein is hemoglobin and fibrous proteins are hair and nails, and collagen.

Nucleic acids  tend to form linear chains from the monomers called nucleotides. Nucleotides have three components:  nitrogenous base. phosphate group, and pentose sugar (5-carbon sugar) that together forms a definite linear shape. It is found in DNA of living organisms.

Hence, the correct option is "A . proteins can take a variety of shapes, and nucleic acids tend to form linear chains".
