DIFFERENCES IN PROTEIN SYNTHESIS IN PROKARYOTES AND EUKARYOTES
between eukaryotic and prokaryotic protein synthesis
1 number of origin site is one in case of prokaryote,and in
case of eukaryotes no of origin site is thousand
2 cell cycle is not differentiated in case of eukaryotes
cell is involed replication take place in s phase
between eukaryotic and prokaryotic protein ..
1. Enzymes for DNA replication only found in eukaryotes are certain types of DNA ploymerases and telomerase.
Enzymes only found in prokaryotes are the different DNA ploymerases and DNA gyrate.
Enzymes common to both are helicase, primase, topoismerase and DNA ligase.
2. Yes in eukaryotesn(linear double stranded DNA) there are multiple origins of replication at which replication forks are formed in replicons. Prokaryotes only have a single origin of replication and thus a single replication fork formed.
3. False. In bacteria, in addition to topoismerase, DNA gyrase also induces negative supercoiling.
4. No nucleus in prokaryotes and hence transcription is coupled to translation (while RNA transcript is being synthesised, a 70s ribosome will attach to the 5' end). True.
Hope is helped. How long ago was this posted?
Comparison between prokaryotes and eukaryotes ..
Difference between Prokaryotic and Eukaryotic Cell: Sr. Prokaryotes. Eukaryotes. Prokaryotes are those organisms which does not contain the nucleus in them. Eukaryotes contain the nucleus in them. The size of an prokaryotic cell lies in between 0. The size of an Eukaryotic cell lies in between 1.
Difference between Prokaryotic and Eukaryotic cells ..
While few single cell and all multicellular organisms are known as Eukaryotes, although they have the cytoplasm and genetic material in common. Prokaryotic cell: They happen to be simpler and smaller. A prokaryotic cell doesn’t possess nucleus or other cell organelles. It is derived from a Greek word – “prokaryote” translating to before nuclei and they reproduce through nuclear fission. It has a capsule which covers the outside of the wall, a cell wall which provides strength and rigidity, cytoplasm helping in cellular growth and a plasma membrane containing proteins, etc. The cytoplasm region contains ribosomes which are the smallest part and play a vital role in protein synthesis, mesosomes or the folding which play a vital role in cellular respirations, plasmids the small circle of DNA, pili and flagella. It is also derived from a Greek word translating to good or true nuclei.
