offspring will be exact genetic copies of the parent. A more stringent definition is agamogenesis which is reproduction without the fusion of gametes. Asexual reproduction is the primary form of reproduction for single-celled organisms such as the archaea‚bacteria‚ and protists. Many plants and fungi reproduce asexually as well. While all prokaryotes reproduce asexually (without the formation and fusion of gametes)‚ mechanisms for lateral gene transfer such as conjugation‚ transformation and transduction

Option F: Microbes and Biotechnology Diversity of Microbe F.1.1 Outline the classification of living organisms into three domains. Three domains of living organisms: 1. Archaea - very primitive; live in extreme habitats 2. Eubacteria - more advanced 3. Eukaryota - all life forms with eukaryotic cells (have a nucleus) Use of ribosomal RNA sequences for classification rRNA is found in all cells rRNA is easy to isolate Analyzed to determine the exact sequence of nucleotide bases

nitrogen with hydrogen to produce ammonia‚ which is then further converted by the bacteria to make their own organic compounds. Most biological nitrogen fixation occurs by the activity of Mo-nitrogenase‚ found in a wide variety of bacteria and some Archaea. Mo-nitrogenase is a complex two component enzyme that has multiple metal-containing prosthetic groups. Some nitrogen fixing bacteria‚ such as Rhizobium‚ live in the root nodules of legumes (such as peas or beans). Here they form a mutualistic relationship

Unit 15 D1 Prokaryotes Prokaryotes have no organized nucleus but instead they their DNA clumped in an area but there is no organized nucleus with a membrane. This is because prokaryotes don’t have mitosis or meiosis like other cells. Scientists don’t really have a good way of describing how they duplicate‚ but it’s not through normal means. It is sometimes called simple mitosis. On the other hand eukaryotes have a nucleus which contains the DNA and the information necessary to grow reproduce and

from the controlled by one factor- the variable. species: A group whose members possess similar anatomical characteristics and have the ability to interbreed. Domain: A taxonomic category above the kingdom level; the three domains of life are Archaea‚ Bacteria and Eukarya. Theory: A widely accepted explanatory idea that is broad in scope and supported by a large body of evidence. Evolutionary Adaptations: an inherited characteristic that enhances an organisms ability to survive and reproduce
