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.
Endocytosis is a cellular process where cells absorb molecules or substances from outside the cell by engulfing it with the cell membrane.This technique is critical to the survival of the cell, since most molecules important to the cell cannot normally pass through the cellâs hydrophobic plasma membrane.inocytosis. In this process, the cell membrane folds around the molecule or substance, and it is dissolved into the interior of the cell. Molecules such as proteins and other water-soluble substances are thus injested this way, which could not otherwise breach the cell membrane.
