The cytoskeleton has many functions. It is made up of different types of proteins that combine to make different types of filaments. The cytoskeletal filaments are dynamic, meaning they can grow and shrink at different parts of the cell and at different rates.
1 Another method of genetic transfer and recombination is transduction. 2  This method involves the transfer of DNA from one bacterium to another with the use of a bacteriophage (phage). 3  A phage is a virus that infects bacteria.
DNA, or deoxyribonucleic acid, is the hereditary genetic material for most living organisms. DNA is present in cells in the form of a double-stranded helix that is composed of long strands of nucleotides. The unique sequence of nucleotides within the DNA molecule stores the genetic information. process by which an organism is genetically changed, resulting in a mutation, which is a change in the DNA sequence of a gene. It may occur naturally, for example, due to natural exposure to ultraviolet (UV) light or chemicals; or it can happen deliberately for the purpose of increasing genetic variation of a species.
