In ALS, also known as amyotrophic lateral sclerosis, the chromosome primarily affected is chromosome 9. A gene called C9orf72 located on this chromosome is linked to a significant percentage of familial ALS cases. Other genetic mutations on different chromosomes can also contribute to ALS development.
Obviously.
Chromosome 2
if you mean chromosome its the 15th......
Chromosome 21 is tripled in Down syndrome.
Chromosome number 8. (Gene: RECQL4 gene.)
nucleus → chromosome → gene
Smallest to largest: Gene (a place on a chromosome); chromosome (there are 46 in human cells); and DNA (because it accounts for all the genetic material in a cell).
Barth syndrome occurs when a person is born with a mutated, or abnormal, TAZ1 (or G4.5) gene. This abnormal gene is located on the X chromosome, which is a sex-determining chromosome. Males have one X and one Y chromosome, while females have two X chromosomes.
Gene duplication is a type of mutation that can add genes to a chromosome. During gene duplication, a segment of DNA is copied and inserted into the chromosome, leading to an increase in the number of copies of a particular gene. This can result in gene families with multiple copies of a gene that may evolve new functions over time.
Chromosome numbers: 1, 14, 19, and 21 are affected by Alzheimer's disease.
The ear lobe trait is not located on a specific chromosome, as it is a common genetic trait that is not influenced by a single gene or located on a specific chromosome. The presence or absence of ear lobes is determined by multiple genetic factors.
