Diploid nuclei of the ascomycete neurospora crassa contain 14 chromosomes. a single diploid cell in an ascus will undergo one round of meiosis, followed in each of the daughter cells by one round of mitosis, producing a total of eight ascospores. if a single, diploid g2 nucleus in an ascus contains 400 nanograms (ng) of dna, then a single ascospore nucleus of this species should contain how much dna (ng), carried on how many chromosomes?

Amount of DNA in a diploid G2 nucleus after S phase has already undergone DNA replication hence the amount of DNA in a diploid nucleus in G1 would be 200 ng. As the organism is diploid, 200 ng of DNA would be carried on 14 chromosomes.  

this protocol provides a detailed procedure for total protein extraction for western blot analysis from achieved samples following trizol isolation of rna.

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .
