Probes for Cloned Genes Use ____

Question

Probes for cloned genes use ____.  
A) complementary nucleotide sequences tagged with a detectable label
B) specific antibodies that kill all the cells
C) specific enzymes that lyse all the cells
D) certain bacteria that glow when they take up the genes
E) DNA ligase

Accepted Answer

Probes for cloned genes typically use complementary nucleotide sequences that are labeled with a detectable label, such as a fluorescent dye or radioactive isotope. These probes are used to hybridize with the target DNA and identify the presence of the cloned gene. This technique is commonly used in molecular biology and genetics research. The other options listed are not commonly used in gene cloning and detection.
