Gram Positive And Negative Bacteria
828 wordsGram Positive and Gram Negative Bacteria It is a well-known fact that bacterial cells, like plant cells, are surrounded by a cell wall. However, few people know that their cell walls are quite different. Bacterial cell walls are made up of polysaccharide chains linked to amino acids. At the same time, plant cell walls are made up of cellulose, which contains no amino acids. In the same way, bacterial cell walls themselves differ from one another. Scientists distinguish two types of bacteria cell...

Genetic Engineering E G
406 wordsBioengineering, or genetic engineering is an altering of genes in a particular species for a particular outcome. It involves taking genes from their normal location in one organism and either transferring them elsewhere or putting them back into the original organism in different combinations. Most biomolecules exist in low concentrations and as complex, mixed populations which it is not possible to work efficiently. This problem was solved in 1970 using a bug, Escherichia coli, a normally innoc...

Nucleic Acid Disease Causing
1,453 wordsThe smallest livingMononucleus Bacteria The smallest living things on earth are the prokaryotic cells. Bacteria fall into the Monera Kingdom. They have a single DNA molecule in the cytoplasm. Almost all minerals have a cell wall that protects the cell and gives it its shape. Some minerals have a layer outside the cell wall called the capsule. This helps the cell cling to surfaces. A typical bacterium is about 2 micrometers long. Inside the cell, there are nucleic acids, enzymes, and other substa...
