What is the difference between a duplicated chromosome and a single chromosome? Best Answer: unduplicated chromosomes are single linear strands, whereas duplicated chromosomes (copied during synthesis phase) contain two copies joined by a centromere.(centromere is a region of DNA t found near the middle of a chromosome where two identical sister chromatids come in contact).

chromosome Definition of chromosome. : any of the rod-shaped or threadlike DNA-containing structures of cellular organisms that are located in the nucleus of eukaryotes, are usually ring-shaped in prokaryotes (such as bacteria), and contain all or most of the genes of the organism; also : the genetic material of a virus — compare chromatin.

Chromosome Chromosomes are large organic molecules that contain most or all of the genetic information of the cell or virus and a great many genes. This threadlike structure is found in the cells of every organism and is responsible for passing of characteristics to offspring is the process of heredity.

Aneuploidy Aneuploidy is the presence of an abnormal number of chromosomes in a cell, such as having 45 or 47 chromosomes when 46 is expected.It does not include a difference of one or more complete sets of chromosomes, which is called euploidy.ost cells in the human body have 23 pairs of chromosomes, or a total of 46 chromosomes. (The sperm and egg, or gametes, each have 23 unpaired chromosomes, and red blood cells have no nucleus and no chromosomes.). One copy of each pair is inherited from the mother and the other copy is inherited from the father.

- Aneuploidy. Aneuploidy is the second major category of chromosome mutations in which chromosome number is abnormal. An aneuploid is an individual organism whose chromosome number differs from the wild type by part of a chromosome set.or example, the aneuploid condition 2 n − 1 is called monosomic (meaning “one chromosome”) because only one copy of some specific chromosome is present instead of the usual two found in its diploid progenitor. The aneuploid 2 n + 1 is called trisomic ,2 n − 2 is nullisomic, and n + 1 is disomic.

- A chromosome (chromo- + -some) is a packaged and organized structure containing most of the DNA of a living organism.t is not usually found on its own, but rather is complexed with many structural proteins called histones as well as associated transcription (copying of genetic sequences) factors and several other macromolecules. Two sister chromatids (half a chromosome) join together at a protein junction called a centromere.

DNA helicase an enzyme that catalyzes the energy-dependent unwinding of the DNA double helix during DNA replication. A gene on chromosome 15q26.1 that encodes a DExH box-containing DNA helicase with both DNA-stimulated ATPase and ATP-dependent DNA helicase activities, which is thought to suppress inappropriate recombination events. gene on chromosome 15q26.1 that encodes a DExH box-containing DNA helicase with both DNA-stimulated ATPase and ATP-dependent DNA helicase activities, which is thought to suppress inappropriate recombination events.

Genetics Terms A reproductive cell or germ cell in sexually reproducing organisms. Gametes are haploid: they carry a single set of unpaired chromosomes. In females they are called eggs, and in males, they are called sperm.

Angelman syndrome This phenomenon is called paternal uniparental disomy. Rarely, Angelman syndrome can also be caused by a chromosomal rearrangement called a translocation, or by a mutation or other defect in the region of DNA that controls activation of the UBE3A gene.These genetic changes can abnormally turn off (inactivate) UBE3A or other genes on the maternal copy of chromosome 15.ost cases of Angelman syndrome are not inherited, particularly those caused by a deletion in the maternal chromosome 15 or by paternal uniparental disomy. These genetic changes occur as random events during the formation of reproductive cells (eggs and sperm) or in early embryonic development.

Chromosome A chromosome (from ancient Greek: χρωμόσωμα, chromosoma, chroma means color, soma means body) is a DNA molecule with part or all of the genetic material (genome) of an organism. Chromosomes are normally visible under a light microscope only when the cell is undergoing the metaphase of cell division.

- Mobile genetic element. (Science: molecular biology) small, mobile dNA sequences that can replicate and insert copies at random sites within chromosomes.

Definitions &Translations Chromosome. A chromosome is an organized structure of DNA, protein, and RNA found in cells. It is a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences. Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions.hromosome. A chromosome is an organized structure of DNA, protein, and RNA found in cells.

Polyploid Polyploidy refers to a numerical change in a whole set of chromosomes. Organisms in which a particular chromosome, or chromosome segment, is under-or overrepresented are said to be aneuploid (from the Greek words meaning not, good, and fold).

- A chromosome mutation is an unpredictable change that occurs in a chromosome. These changes are most often brought on by problems that occur during meiosis (cell division process of gametes) or by mutagens (chemicals, radiation, etc.). chromosome mutation that results in individuals with more than one haploid set of chromosomes in a cell is termed polyploidy. A haploid cell is a cell that contains one complete set of chromosomes.

Genomic imprinting A phenomenon in which the phenotype of the offspring depends on the source of the chromosome containing the imprinted gene, i.e. whether it is from the female or from the male parent. Supplement. Epigenetic factors can cause genomic imprinting. An imprinted gene is one in which the DNA is methylated.
