Does a prokaryotic cell have rna
WebEukaryotic cells have applied the mechanics of RNA splicing to generate the protein diversity necessary to meet their multiple demands. Thus, in contrast with the original definition of a gene in which only one transcript is produced, complex genes can generate multiple protein isoforms from multiple RNA transcripts through alternative splicing ... WebThe mRNAs found in prokaryotes differ from that of eukaryotes in the following ways: (i) The prokaryotic mRNAs are broken down by the ribonuclease into ribonucleotide, hence these are very short lived e.g. 2 minutes in E.coli. The short lived nature is due to changes in environmental conditions.

The division between prokaryotes and eukaryotes is usually considered the most important distinction or difference among organisms. The distinction is that eukaryotic cells have a "true" nucleus containing their DNA, whereas prokaryotic cells do not have a nucleus. Both eukaryotes and prokaryotes contain large RNA/protein structures called ri… WebThe Prokaryotic Cell Recall that prokaryotes are unicellular organisms that lack membrane-bound organelles or other internal membrane-bound structures (Figure 2). Their chromosome—usually single—consists of a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid .
