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.
All living cells must carry out cellular respiration. It can be aerobic respiration in the presence of oxygen or anaerobic respiration. Prokaryotic cells carry out cellular respiration within the cytoplasm or on the inner surfaces of the cells.More emphasis here will be placed on eukaryotic cells where the mitochondria are the site of most of the reactions.f oxygen is present in the cell, then the cell can subsequently take advantage of aerobic respiration via the TCA cycle to produce much more usable energy in the form of ATP than any anaerobic pathway. Nevertheless, the anaerobic pathways are important and are the sole source of ATP for many anaerobic bacteria.
