At about 21.5 genes per megabase, chromosome 11 is one of the most gene-rich, and disease-rich, chromosomes in the human genome. More than 40% of the 856 olfactory receptor genes in the human genome are located in 28 single-gene and multi-gene clusters along the chromosome.
Two copies of chromosome 11, one copy inherited from each parent, form one of the pairs. Chromosome 11 spans about 135 million DNA building blocks (base pairs) and represents between 4 and 4.5 percent of the total DNA in cells.
Each chromosome has a distinct banding pattern, and each band is numbered to help identify a particular region of a chromosome. This method of mapping a gene to a particular band of the chromosome is called cytogenetic mapping. For example, the hemoglobin beta gene (HBB) is found on chromosome 11p15.4.
Legend: Magenta and green. These regions reflect the unique patterns of light and dark bands seen on human chromosomes that have been stained to allow viewing through a light microscope. Red. The centromere, or constricted portion, of each chromosome. Yellow.
23 mar 2006 · We prepared chromosome-specific bacterial artificial chromosome (BAC; CMB9) and fosmid (CMF9) libraries by using flow-sorted chromosomal DNA derived from human chromosomes 9–12 (these ...
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body or the code for functional ribonucleic acid (RNA) molecules. Chromosomes are structures within cells that contain a person's genes.
What are chromosomes and genes, and how are the two related? Describe human chromosomes and genes. Explain the difference between autosomes and sex chromosomes.
