While a eukaryote has a nucleus, the prokaryotic does not. The eukaryotic cell will wrap it's dna around histones, which are a type of protein. The prokaryotic cell combines multiple proteins which fold and condense it's DNA, which then coil up and wrap around the HU protein.

Are ribosomes found in muscle tissue?
Ribosomes are microscopic organelles consisting of RNA and proteins. They are found in the cytoplasm of living cells, including muscle tissues.
What type of RNA is most abudant?
Ribosomal RNA. rRNA.
What is RNA processing?
1.the RNA processing transcribed from a eukaryotic gene is precessed before leaving the nucleus to serve as messenger RNA (rRNA). intro are spliced out, and a cap and tail are added. 1.the RNA processing transcribed from a eukaryotic gene is precessed before leaving the nucleus to serve as messenger RNA (rRNA). intro are spliced out, and a cap and tail are added.
What is the r role of 23S rRNA of 50S RNA?
the 50S rRNA particle forms the large subunit of E. coli ribosomes while the 23S rRNA is a component of the 50S rRNA.
What is the difference between mrna trna and rrna?
These are all terms for types of RNA, or ribonucleic acid. The difference is that mRNA is messenger RNA, tRNA is transfer RNA, and rRNA is ribosomal RNA.
Differences between eukaryotic cells and prokaryotic cells are .?
Eukaryotic cells have a true nucleus, bound by a double membrane. Prokaryotic cells have no nucleus. The purpose of the nucleus is to sequester the DNA-related functions of the big eukaryotic cell into a smaller chamber, for the purpose of increased efficiency. This function is unnecessary for the prokaryotic cell, because its much smaller size means that all materials within the cell are relatively close together. Of course, prokaryotic cells do have DNA and DNA functions. Biologists describe the central region of the cell as its "nucleoid" (-oid=similar or imitating), because it's pretty much where the DNA is located. But note that the nucleoid is essentially an imaginary "structure." There is no physical boundary enclosing the nucleoid.Eukaryotic DNA is linear; prokaryotic DNA is circular (it has no ends).Eukaryotic DNA is complexed with proteins called "histones," and is organized into chromosomes; prokaryotic DNA is "naked," meaning that it has no histones associated with it, and it is not formed into chromosomes. Though many are sloppy about it, the term "chromosome" does not technically apply to anything in a prokaryotic cell. A eukaryotic cell contains a number of chromosomes; a prokaryotic cell contains only one circular DNA molecule and a varied assortment of much smaller circlets of DNA called "plasmids." The smaller, simpler prokaryotic cell requires far fewer genes to operate than the eukaryotic cell.Both cell types have many, many ribosomes, but the ribosomes of the eukaryotic cells are larger and more complex than those of the prokaryotic cell. Ribosomes are made out of a special class of RNA molecules (ribosomal RNA, or rRNA) and a specific collection of different proteins. A eukaryotic ribosome is composed of five kinds of rRNA and about eighty kinds of proteins. Prokaryotic ribosomes are composed of only three kinds of rRNA and about fifty kinds of protein.The cytoplasm of eukaryotic cells is filled with a large, complex collection of organelles, many of them enclosed in their own membranes; the prokaryotic cell contains no membrane-bound organelles which are independent of the plasma membrane. This is a very significant difference, and the source of the vast majority of the greater complexity of the eukaryotic Cell. There is much more space within a eukaryotic cell than within a prokaryotic cell, and many of these structures, like the nucleus, increase the efficiency of functions by confining them within smaller spaces within the huge Cell, or with communication and movement within the Cell.Eukaryotic Cells are the largest Cells, while prokaryotic Cells are smaller than eukaryotic Cells. A eukaryotic Cell is about 10 times bigger than a prokaryotic Cell.Eukaryotic Cells have a bi-lipid-layer plasma membrane and an exterior glyco-callyx Cell Coat; prokaryotic Cells have a bi-lipid-layer plasma membrane and an exterior mostly cellulosic Cell Wall.A List:Prokaryotic cells:Most primitive, earliest form of lifeDo not have a pre-defined nucleusChromosomes are dispersed in the cytoplasmContain no membrane-bound organellesHave circular chromosomes and lack histone proteinsMost metabolically diverseSmall - typically 0.2-2.0 micrometers in diameterHave a primitive cytosketetal structures or don't have a cytoskeleton at allSmaller (70S) ribosomesDon't undergo meiosis but reproduce sexually by the transfer of DNA fragments through conjugationEukaryotic cells:More complex, evolved organsimsContain true nuclei in which chromosomes are compacted as chromatinContain membrane-bound organellesHave linear DNA and contain histone proteinsLarger - typically 10-100 micrometers in diameterHave a complex cytosketetonLarger (80S) ribosomReproduce sexually with the use of meiosis

The sites A P and E are occupied by amino acids being assembled into a chain of polypeptide what are they part of?
The A, P and E sites are part of the prokaryotic ribosome, specifically, the 16S rRNA of its 30S subunit.
RRNA is always attached to the rough ER?
No . cytoplasm also contain rrna .
What is meant by 16s rDNA?
Ribosomal 16S RNA found in the bacteria and small microorganisms prokaryotic cells and the subunit is 30S.
