The Genomic Structure of Arabidopsis thaliana

See background information about the structure of chromosomes. The genome of Arabidopsis thaliana consists of 5 chromosomes, one circular mitochondrial DNA, and a circular chloroplast DNA. Chromosomes are often drawn as in Figure 1 below: with a short and long arm and an intervening centromeric region. Figure 2 depicts the shapes and relative sizes of the A. thaliana chromosomes. Table 1 shows the size (in Mbp) and predicted number of genes for each chromosome.
