FIG. 3.

Analysis of the transcription initiation site of the pfs16 gene. RNase protection was performed on RNA of the different developmental stages of P. falciparum and on yeast RNA as indicated. An arrow indicates the position of the major protected fragment. The letters G, A, T, and C indicate the products of a sequencing reaction that was run along the protected fragments for size determination. Note that the sequence depicted in the figure does not contain a single cytosine base.
