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.
Based on the organization of their cellular structures, all living cells can be divided into two groups: prokaryotic and eukaryotic (also spelled procaryotic and eucaryotic). Animals, plants, fungi, protozoans, and algae all possess eukaryotic cell types. Only bacteria have prokaryotic cell types. Eukaryotic cells are generally much larger and more complex than prokaryotic. Because of their larger size, they require a variety of specialized internal membrane-bound organelles to carry out metabolism, provide energy, and transport chemicals throughout the cell. Eukaryotic cells contain a variety of internal membrane-bound organelles that are not a part of the endomembrane system. These include mitochondria, chloroplasts, lysosomes, peroxisomes, vacuoles, and vesicles. We will now look at chloroplasts.
