Answer #1

ANSWER:

(a) Escherichia coli

Experimental material within the study of desoxyribonucleic acid replication has been E. coli. E-coli absolutely taggedwith 15N is allowed to grow in 14N medium. the 2 strands of desoxyribonucleic acid molecule of the primary generation microorganism have completely different density and don't agree parent desoxyribonucleic acid. Meselson and Stahl, 1958 by mistreatment 14N and 15N confirmed that the replication of desoxyribonucleic acid in E-coli is semi-conservative in nature.

What is a major difference between eukaryotic DNA replication and prokaryotic DNA replication? a. DNA pol III of eukaryotes has both exonuclease activities while prokaryotic DNA pol III does not. b. There are many more types of prokaryotic DNA polymerases. c. Prokaryotic replication does not require a primer. d. Prokaryotic chromosomes are circular and so have no telomeres; eukaryotic chromosomes have telomeric replication.
