Membrane bound organelles,DNA enclosed by the nuclear envelope.Much of eukaryotes are multicellular, although there are types of single celled eukaryotes.Eukaryotes are also larger than the prokaryotes.Eukaryotes have introns, a noncoded region in the DNA that is taken out during transcription.
eukaryotes have nuclei and Golgi bodies
There are two basic types of cells, prokaryotes and eukaryotes. Eukaryotes differ from prokaryotes in a few ways, but the biggest difference is that eukaryotes have a nucleus and prokaryotes don't.
Prokaryotes and Eukaryotes
mitosis and miosis
The ribosome has two subunits; a smaller one and a bigger one. The smaller one contains 21 proteins and one rRNA molecule, and the larger subunit contains 34 proteins and two rRNA molecules. Ribosomes are found in prokaryotes and eukaryotes (although they are a little different, they have the same function). Ribosomes are made of nucleolus. Some people might think that mRNA also helps to form the structure of the ribosome, but this is not the case. rRNA makes up the ribosome of a cell, while mRNA travels to the ribosome of a cell during protein synthesis in order to code for the amino acids. Only during protein synthesis will the mRNA appear in a ribosome. mRNA does not make up the structure of the ribosome! Hope this helps! RNA and proteins
eukaryotes have nuclei and Golgi bodies
Haploid eukaryotes have one set of chromosomes, while diploid eukaryotes have two sets. This means haploid cells have half the genetic material of diploid cells. Haploid eukaryotes are typically found in reproductive cells, like sperm and eggs, while diploid eukaryotes are found in most other cells of the body.
Protein synthesis in eukaryotes occurs in the cytoplasm and involves two main steps: transcription and translation. During transcription, the DNA in the nucleus is copied into messenger RNA (mRNA) by RNA polymerase. The mRNA then travels to the ribosomes in the cytoplasm, where translation takes place. During translation, transfer RNA (tRNA) molecules bring amino acids to the ribosome, where they are assembled into a protein based on the sequence of codons on the mRNA. This process continues until the entire protein is synthesized.
All eukaryotes share the characteristics of having membrane-bound organelles and a true nucleus containing their genetic material. These features distinguish eukaryotic cells from prokaryotic cells, which lack a nucleus and membrane-bound organelles.

One mRNA strand is made.
The transcription in eukaryotes, a much more complex process than in prokaryotes. In eukaryotes, transcription and translation take place in different cellular compartments:transcription takes place in the membrane-bounded nucleus, whereas translation takes place outside the nucleus in the cytoplasm. In prokaryotes, the two processes are closely coupled. Indeed, the translation of bacterial mRNA begins while the transcript is still being synthesized. The spatial and temporal separation of transcription and translation enables eukaryotes to regulate gene expression in much more intricate ways, contributing to the richness of eukaryotic form and function.A second major difference between prokaryotes and eukaryotes is the extent of RNA processing. Although both prokaryotes and eukaryotes modify tRNA and rRNA, eukaryotes very extensively process nascent RNA destined to become mRNA. Primary transcripts (pre-mRNA molecules), the products of RNA polymerase action, acquire a cap at their 5′ ends and a poly(A) tail at their 3′ ends. Most importantly, nearly all mRNA precursors in higher eukaryotes are spliced. Introns are precisely excised from primary transcripts, and exons are joined to form mature mRNAs with continuous messages. Some mRNAs are only a tenth the size of their precursors, which can be as large as 30 kb or more. The pattern of splicing can be regulated in the course of development to generate variations on a theme, such as membrane-bound and secreted forms of antibody molecules. Alternative splicing enlarges the repertoire of proteins in eukaryotes and is a clear illustration of why the proteome is more complex than the genome.
