To screen the genome of a bacterium for a particular gene,you would use ________that attach to complementary DNA sequences.
A) gels
B) ligases
C) DNA probes
D) restriction enzymes

Question

Quizplus · Accepted Answer

DNA probes are short strands of single-stranded DNA that are complementary to the sequence of the target gene. By hybridizing with the target sequence, they can identify and locate the gene of interest in a complex mixture of genomic DNA. Gels are used for separating DNA fragments based on size, ligases are used for joining DNA fragments together, and restriction enzymes are used for cutting DNA at specific sites. While these techniques may be used in conjunction with DNA probes, they are not specifically designed for screening a genome for a particular gene.
