Overlapping Genomic Clones Found in Physical Chromosome Maps are Also

Question

Overlapping genomic clones found in physical chromosome maps are also known as:
A) STSs
B) Contigs
C) ORI sites
D) Polylinkers
E) All of these

Accepted Answer

Overlapping genomic clones found in physical chromosome maps are referred to as contigs. STSs (A) stands for Sequence Tagged Sites, which are short DNA sequences that are unique to a specific location in the genome. ORI sites (C) are origins of replication, where DNA replication initiates. Polylinkers (D) are DNA sequences that contain multiple restriction enzyme recognition sites, used to facilitate cloning.
