A congenital endocrine condition caused by the presence of an extra X chromosome is?
DOWNS Syndrome.
What happens when Nondisjuntion during meiosis at the 21 chromosome?
The most common deffect that will occur with there is nondisjunction on the 21st chromosome is downs syndrome. Downs syndrome is a mental illness that can cause some physical abnormalities such as a large forhead, but also some intellectual delays.
What is the genetic disorder associated with chromosome 5 monosomy?
The most common condition associated with a deletion of the end of chromosome 5 is: cri-du-chat syndrome.
At the beginning of cell division DNA and the proteins associated with the DNA coil into a structure called an?
At the beginning of cell division, DNA and the proteins associated with the DNA coil into a structure called a chromosome. Chromosomes are visible under a microscope and contain the genetic material (DNA) of an organism.
What is the difference between a kid with Down syndrome and a kid without Down syndrome?
downs syndrome is a a chromosome abnormality in which their is an extra copy of the 21st chromosome causing the person to have a flatter face slanted eyes and a mental handicap.
What gene is associated with Periventricular heterotopia?
Periventricular heterotopia is associated with abnormalities of the filamin1 gene on the X chromosome.
Which chromosomal abnormality is associated with part of a chromosome breaking away and attaching to a non-homologous chromosome?
The chromosomal abnormality associated with a part of a chromosome breaking away and attaching to a non-homologous chromosome is called a translocation. This can lead to various genetic disorders and cancers, such as chronic myelogenous leukemia (CML), where a piece of chromosome 9 and chromosome 22 exchange places, forming the Philadelphia chromosome. Translocations can disrupt gene function and regulation, potentially resulting in significant health issues.
What is translocation downs syndrone?
Translocation Down syndrome is a genetic condition caused by the presence of an extra chromosome 21 due to a rearrangement of genetic material between chromosomes. Unlike the more common forms of Down syndrome, which result from an extra full chromosome 21, translocation Down syndrome occurs when a portion of chromosome 21 becomes attached to another chromosome. This can happen during the formation of reproductive cells or in early fetal development. Individuals with translocation Down syndrome typically exhibit the same physical and cognitive characteristics associated with Down syndrome.
DNA and the proteins associated with the DNA coil into a structure called?
chromosome
Do animals have chromosome 21?
Yes, animals have chromosome 21. It may vary in size or gene content depending on the species. In humans, chromosome 21 is associated with conditions such as Down syndrome.
Where did down syndrome come from?
Downs syndrome is a genetic abnormality caused by an extra chromosome, in simple terms - as a healthy individual you inherit 22 chromosomes from your mother and 22 from your father, so that's 44 altogether, 1 chromosome from each of your parents will combine to form 22 sets, in a person with Downs syndrome there is an extra abnormally shaped set of chromosomes. So in short a person with Downs syndrome has 23 chromosomes instead of 22.
Are genetic defect associated with abnormalities of autosomes or of sex chromosomes?
Genetic defects can be associated with autosome and chromosome abnormalities.
