The set of veins inside the rectum when distended result in internal hemorrhoids and the set of veins under the skin around the anus when distended result in External Piles. Some other factors also contribute to the prolepses of the veins.
Protein synthesis is a very important process for both eukaryotes and prokaryotes. In this process, nucleotide sequence in a segment of DNA is translated into the specific sequence of amino acids in a protein.Translation occurs at ribosomes; ribosomes consist of RNA and proteins. While eukaryotic cells have 80S ribosomes, bacterial cells contain 70S ribosomes, which have the folllowing components.enetic information in bacteria is stored in the sequence of DNA in two forms, that is bacterial chromosome and plasmid. The following are the properties of a bacterial chromosome. 1  Location: Within nucleoid region, not surrounded by nuclear envelope. 2  Number: 1 chromosome each cell.
In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes.Each of these organelles performs a specific function critical to the cell's survival.Moreover, nearly all eukaryotic organelles are separated from the rest of the cellular space by a membrane, in much the same way that interior walls separate the rooms in a house.n eukaryotes, however, the DNA takes the form of compact chromosomes separated from the rest of the cell by a nuclear membrane (also called a nuclear envelope). Eukaryotic cells also contain a variety of structures and organelles not present in prokaryotic cells.
