A chromosome is a collection of many genes and protein substrates upon which the genes are strung, rather like beads on a string.
Chromosome 2
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).
homologous chromosomes
When a gene is linked to a chromosome, it means that the gene is physically located on that chromosome. This means that the gene is inherited along with the chromosome it is located on, and may be inherited together with other nearby genes on the same chromosome.
no, the gene is not actually the chromosome but a part of chormosome...
The specific location of a gene on a chromosome is called it's locus.
Thalassemia is carried on chromosome 11 and chromosome 16, depending on the type. The alpha-thalassemia gene is located on chromosome 16, while the beta-thalassemia gene is found on chromosome 11. Mutations in these genes affect the production of hemoglobin, leading to the various forms of thalassemia.
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.
The HBB gene, which codes for the beta globin protein, is located on chromosome 11.
chromosome 1 chromosome 1
It is a gene located on either sex chromosome (X or Y chromosome).
