FIG. 3.

Alignment of the vTR sequences of different MDV strains and the chicken telomerase RNA subunit. The primary sequences of vTR and cTR were aligned by using conserved sequences as anchors. Each line consists of 70 characters. Identical nucleotides are shown in uppercase, point mutations are in lowercase and gray boxes, and deletions are indicated by dashes. The conserved domains of the cTR and vTR genes (CR) are boxed in black, functional boxes are underlined and shown in boldface, and junction regions (J) are underlined.
