If Escherichia coli,grown for a period of time in 15N,is transferred to 14N for one generation of DNA replication,the resulting DNA should have 14N added to all "new" DNA.If semiconservative replication is occurring,the 14N-containing "new" DNA will compose:

A) one strand of all bacterial chromosomes. B) both strands of DNA in half of all bacterial chromosomes. C) regions dispersed throughout all bacterial DNA. D) none of the new DNA;it will only be found in the old DNA. E) None of the answer options are correct. A) one strand of all bacterial chromosomes. B) both strands of DNA in half of all bacterial chromosomes. C) regions dispersed throughout all bacterial DNA. D) none of the new DNA;it will only be found in the old DNA. E) None of the answer options are correct.

If Escherichia coli,grown for a period of time in 15N,is transferred to 14N for one generation of DNA replication,the resulting DNA should have 14N added to all "new" DNA.If conservative replication is occurring,the 14N-containing "new" DNA will compose:

A) one strand of all bacterial chromosomes. B) both strands of DNA in half of all bacterial chromosomes. C) regions dispersed throughout all bacterial DNA. D) none of the new DNA;it will only be found in the old DNA. E) All of the answer options are correct. A) one strand of all bacterial chromosomes.
