D) a SNP
E) a fragment

Question

Quizplus · Accepted Answer

A probe is used to locate a gene of interest in an established DNA library. The probe is a single-stranded nucleic acid molecule that binds to a complementary sequence in the target gene and can be detected through a labeling system. This allows for the identification and isolation of the clone containing the gene of interest. Vectors are used to carry the gene of interest into host cells, clones are made by inserting DNA fragments into vectors, SNPs are variations in a single nucleotide at a specific location in the DNA, and fragments are pieces of DNA that are produced by restriction enzymes.
