Eukaryotic chromosomes

Identify a gene locus and its protein product

Type the name of a gene such as DRDR or CFTR (see Oxford textbook page 154 for more examples) or type and search for "potassium channel". A gene loci has:

The chromosome number
The chromosome's arm (p=short and q=long)
The position in the arm (band) counting from the centromere.

Chromosome MapOur genetic information is stored in 23 pairs of chromosomes that vary widely in size and shape. Chromosome 1 is the largest and is over three times bigger than chromosome 22. The 23rd pair of chromosomes are two special chromosomes, X and Y, that determine our sex. Females have a pair of X chromosomes (46, XX), whereas males have one X and one Y chromosomes (46, XY). Chromosomes are made of DNA, and genes are special units of chromosomal DNA. Each chromosome is a very long molecule, so it needs to be wrapped tightly around proteins for efficient packaging.
