Explanation:
Genetic recombination is the process by which a strand of genetic material (usually DNA, but can also be RNA) is cut and then attached to a molecule of different genetic material. In eukaryotes, recombination commonly occurs during the meiosis of sexual reproduction3 (the process by which eukaryotes generate gametes), such as chromosomal cross-linking between paired chromosomes. This process leads to the progeny having combinations of genes different from those of their parents and can produce chimeric alleles. In evolutionary biology it is believed that this mixture of genes has several advantages, including that it allows organisms to reproduce sexually and avoid Muller's ratchet. In vertebrates there is also a type of special genetic recombination in B and T cells of the immune system, called recombination V (D) J, which is responsible for generating the tremendous variability of antibodies and T-cell receptors necessary for the response immune. Site-specific recombination is a special type of homologous recombination that occurs in specific, short and homologous regions, existing in both fragments to recombine. It is usually typical of viruses, which use it to integrate into the host genome.
Answer:
The outer pleura is attached to the chest wall (1-9). The pleural cavity aids optimal functioning of the lugs during breathing. It transmits movements of the chest wall to the lungs, particularly during heavy breathing.
The answer is 1, because while organic compounds contain carbon, inorganic compounds do not.
Answer:
i think it's C
Explanation:
meiosis is with sex cells and the resulting cells don't have paired chromosomes, making them haploid, and other cells have a complete set of chromosomes after mitosis, making them diploid.
