Genetics Exam 4 Review Chapter 13 and 14

TELOMERASE

• A protein that has a small piece of RNA

• A small piece of protein that has DNA

• Add many copies of short DNA sequence to end of chromosome

• Add many copies of short RNA sequence to the end of the chromosome

Three steps to TELOMERASE

• BINDING

• POLYMERIZATION OF NDTPS

• TRANSLOCATION

• DISSOCIATION

TELOMERASE binds to the (a)   over hanging region.
