Figure 1: Comparative organisation of the chick, mouse, and human RhoA genes. Introns are indicated by their respective name and size above the cDNA line diagram and positioned as indicated by the nucleotide numbers below. Nucleotide position 1 refers to the A in the first in-frame ATG in the RhoA coding sequence. The open reading frame (ORF) is shown in black, with the start and stop codons and their respective nucleotide position shown below. The 5′ and 3′ untranslated regions (UTR) are depicted in grey.
