Multiple Choice
A radioactive probe is generated using the actin gene from yeast.This probe is used in a Southern blot analysis of EcoRI digested genomic DNA from the ciliated protozoan Tetrahymena thermophila.The autoradiogram shows a single-labeled band of 4 kb in size.This means that the Tetrahymena actin gene is:
A) 4 kb in size.
B) the same size as the yeast gene.
C) present in one copy in the genome.
D) present in four copies in the genome.
E) identical in sequence with the yeast gene.
