Bacteria are single celled microbes. The cell structure is simpler than that of other organisms as there is no nucleus or membrane bound organelles. Instead their control centre containing the genetic information is contained in a single loop of DNA. Some bacteria have an extra circle of genetic material called a plasmid. The plasmid often contains genes that give the bacterium some advantage over other bacteria. For example it may contain a gene that makes the bacterium resistant to a certain antibiotic.
Bacteria are classified into 5 groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). They can exist as single cells, in pairs, chains or clusters.
A hot spot is here magma appears near to the surface. Imagine this, the crust is a plate, and the hotspot is a pencil, as the plate moves, you punch holes through the plate. This is the hotspot creating volcanoes as the crust moves. This is how hotspot volcanoes are created. The volcanoes that are created on boundaries are created from differences in the crust as it is created.
Answer:
Chromosomes will not align at the equator of the cell, and subsequently will not separate to opposite poles.
Explanation:
Mitosis is a cellular division that results in daughter cells with identical copies of the genetic material as the parent cell. Mitosis is characterized by different stages viz: Prophase, Metaphase, Anaphase, and Telophase. The centromere is a very important part of the cell during division as it produces microtubules that grows out and bind to the kinetochore of each chromosome, hence, aligning them at the CELL PLATE (cell equator) and subsequently pulls them apart to opposite poles. This alignment and pulling apart occurs during METAPHASE and ANAPHASE respectively.
Mutation is any change that occurs in the nuceleotide sequence of the genetic material (DNA). If a change/mutation occurs leading to a defective or non-functional centromere, the centromere will no longer be able to produce microtubules that will bind to the kinetochores of each chromosome. Therefore, the chromosomes will be unable to align at the equator/middle of the cell and most importantly, inability to separate to opposite poles, which is the main point of Mitosis.
