Answer 1

At the end of the arms

Question 2

What is the end replication problem?

Answer 2

Consecutive rounds of DNA replication cause the telomeres to become shorter and shorter

Question 3

How do eukaryotes solve the end replication problem?

Answer 3

Telomerase can reverse transcribe its own RNA template to synthesis the additional DNA, increases the 3’ end of the parent strand, allowing the okasaki fragments and polymerase to extend the 5’ end if the other DHA strand.

Question 4

What is telomerase made up of?

Answer 4

Proteins and RNA
