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.
The presence of a nucleus gives eukaryotes their name, which comes from the Greek ÎµÏ (eu, well) and ÎºÎ¬ÏÏÎ¿Î½ (karyon, nut or kernel). Eukaryotic cells also contain other membrane-bound organelles such as mitochondria and the Golgi apparatus. In addition, plants and algae contain chloroplasts.Eukaryotic organisms may be unicellular, or multicellular. Only eukaryotes have many kinds of tissue made up of different cell types.here are many different types of eukaryotic cells, though animals and plants are the most familiar eukaryotes, and thus provide an excellent starting point for understanding eukaryotic structure. Fungi and many protists have some substantial differences, however.
