There exist many more eukaryotic initiation factors (eIF) than prokaryotic initiation factors due to greater biological complexity. Processes eIF is involved in include: formation of initiation complexes with 5' mRNA and..

how is RNA processing a great way of controlling gene expression in eukaryotes vs. prokaryotes? The Double Life of RNA: The Discovery of Ribozymes Dr. Thomas Cech dicusses RNA, its characteristics, and its ability to act as an enzyme. www.hhmi.org .
There are how many different kinds of RNA codons? communicated? Through transcription, which is the process where DNA information is coded into RNA, and translation which is the process of converting the mRNA molecule by ribosome into polypeptide strand. This process happens in both prokaryotic and eukaryotic cells, but in Eukaryotic cells translation takes place outside of the nucleus. Professor Wolfe also discusses the three different types of RNA, mRNA, tRNA, and rRNA. He explains rRNA and how is used to help translate the mRNA. This ...
Question : i am talking about the transcription in gene expression.
Answer : I think the general process is basically the same. The only differences I can think of are that prokaryotes don't have introns and they also don't have membrane bound compartments, which the RNA pass through in eukaryotes.

Question : Question asks:
Unlike prokaryotic DNA replication, eukaryotic DNA replication __________.
(A) is completed by DNA polymerase
(B) cannot be completed by DNA polymerase
(C) is semiconservative
(D) has a single origin
(E) is error free
I know that both of them are completed by DNA polymerase and that only prokaryotes have a single origin. I chose C but I'm not sure if D is incorrect. (Unfortunately, the answer given is '0'...which doesn't make any sense!)
Answer : The answer is B, although it isn't entirely correct. Eukaryotic DNA replication runs into a problem at the end of the chromsome (at the telomere) as stated by bio. There is a special enzyme complex called telomerase which is composed of a couple of subunits and an RNA primer molecule, which technically makes telomerase an RNA-dependent DNA polymerase (a reverse transcriptase) that replicates the telomere region. So, a different type of DNA polymerase (telomerase) actually completes the replication at the ends of the chromosomes. So, saying that DNA polymerase cannot complete eukaryotic DNA replication is somewhat correct if you consider telomerase to not be the standard DNA polymerase (even though it is a type of DNA polymerase, an RNA-dependent DNA polymerase).
