Asexual reproduction is reproduction which does not involve meiosis (reduction division in which the number of chromosomes per cell is halved) and/or fertilization (fusion of gametes to produce a new organism). Certain types of starfish reproduce asexually by means of fragmentation (breaking of their body into fragments), followed by regeneration (the re-growing of lost body parts).

nucleotide bases are the parts of DNA and RNA that may be involved in pairing. The main ones are cytosine, guanine, adenine (DNA and RNA), thymine (DNA) and uracil (RNA), abbreviated as C, G, A, T, and U, respectively. They are usually simply called bases in genetics, that are used to carry heredity information.
