The tips of eukaryotic chromosomes, made of repeated non coding sequences that protect the ends from loss during replication, are called
Correct answer: C. telomeres
- A. centromeres
- B. kinetochores
- C. telomeres
- D. nucleosomes
Explanation
Telomeres shorten a little with every division and act like the plastic tips of shoelaces, preventing the loss of essential genes and stopping chromosome ends from sticking together. Cells with active telomerase, such as germ cells and many cancer cells, maintain them.

About Animal and Plant Cell
Animal and plant cells share a plasma membrane, cytoplasm, nucleus, ribosomes, mitochondria and endoplasmic reticulum, but plant cells also have a cellulose cell wall, chloroplasts and a large permanent vacuole. Questions cover organelle structure and function, differences between the two cell types, and how membranes control movement of substances.
