Which of the following statements is true regarding somatic cell nuclear transfer (SCNT) experiments? Choose one option below. a. They established that some genes are gradually lost as the cells differentiate into specialized tissues. b. They confirmed that a somatic cell has all the genetic information necessary to make any other cell type in the body. c. The highest efficiency of SCNT was achieved when nuclei from permanently differentiated cells (rather than early embryonic cells) were fused with the enucleated eggs.
