Summary Introduction
To review:
The blank space given in a statement, “Telomerase synthesizes DNA in the _______ direction.”
Introduction:
Telomerase is a ribonucleoprotein referred to as terminal transferase and is composed of an RNA (ribonucleic acid) and protein. The telomerase is required for termination of replication and maintain chromosomal ends.

People who carry a theoretical genetic disorder (called B-disease) can be identified from a 2kb DNA sequence. People who carry this genetic disorder have a single nucleotide polymorphism that results in a change of GTATCC to GGATCC, a site that only occurs once at nucleotide number 750 in this DNA sequence. Answer the following questions based on the information provided. (a) How can you develop a simple molecular test with enzyme BamH to identify the genetic disorder?
