A chromatid is one of the two identical halves of a chromosome that has been replicated in preparation for cell division. The two "sister" chromatids are joined at a constricted region of the chromosome called the centromere. During cell division, spindle fibers attach to the centromere and pull each of the sister ...

Gene - Wikipedia A human chromosome can have up to 500 million base pairs of DNA with thousands of genes. In biology, the word gene (from Greek: γένος, génos; [1] meaning generation [2] or birth [1] or gender) can have several different meanings. The Mendelian gene is a basic unit of heredity and the molecular gene is a sequence of nucleotides in DNA that ...

Genetic Linkage - University of Utah A chromosome is a single piece of DNA. Genes are segments of DNA arranged along a chromosome. A single chromosome can have hundreds or even thousands of genes. Most sexually reproducing organisms, like people and pigeons, have two copies of each chromosome, called homologous chromosomes. Humans have 23 chromosome pairs, or 46 chromosomes … Diatom - Wikipedia Reproduction and cell size. Reproduction among these organisms is asexual by binary fission, during which the diatom divides into two parts, producing two "new" diatoms with identical genes.Each new organism receives one of the two frustules - one larger, the other smaller - possessed by the parent, which is now called the epitheca; and is used to construct a second, smaller frustule, the ... 1.

List of organisms by chromosome count - Wikipedia The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms.This number, along with the visual appearance of the chromosome, is known as the karyotype, and can be found by looking at the chromosomes through a microscope.Attention is paid to their length, the position of the centromeres ...

Centromere - Genome.gov That thin part is the centromere. The centromere is not always in the middle of the chromosome. In fact, sometimes it can be almost all the way at the top. That is called an "acrocentric chromosome." What you can't see is the very special kind of DNA that makes up the centromere. It is a specific kind of repetitive DNA, called "alpha satellite." › watchEukaryopolis - The City of Animal Cells: Crash Course Biology #4 Hank tells us about the city of Eukaryopolis - the animal cell that is responsible for all the cool things that happen in our bodies.Table of Contents time c...

Metaphase - Genome.gov Definition. Metaphase is a stage during the process of cell division (mitosis or meiosis). Normally, individual chromosomes are spread out in the cell nucleus. During metaphase, the nucleus dissolves and the cell's chromosomes condense and move together, aligning in the center of the dividing cell. At this stage, the chromosomes are ...

Chromosome - Genome.gov A fruit fly, for example, has four pairs of chromosomes, while a rice plant has 12 and a dog, 39. In humans, the twenty-third pair is the sex chromosomes, while the first 22 pairs are called autosomes. Typically, biologically female individuals have two X chromosomes (XX) while those who are biologically male have one X and one Y chromosome (XY).
