Definitions:

Eukaryotic Chromosomes

Linear structures found in the nucleus of eukaryotic cells, made up of DNA and proteins, that contain genes and function in heredity and gene expression.

Telomerase

An enzyme that adds DNA sequence repeats to the ends of DNA strands in the telomere regions, which are found at the ends of eukaryotic chromosomes. This activity can preserve the length of chromosomes and has implications in aging and cancer.

Lengthened

Describes something that has been made longer in duration or size.

Telomere
