Question

True or false? The same telomere sequence is found throughout vertebrates, and similar sequences are found in most other organisms.

Answer 1

Telomeres are repetitive sequences found at the ends of linear chromosomes. While similar telomere sequences are found in most organisms, they are not exactly the same throughout all species.

Step-by-step explanation:

Telomeres are repetitive sequences found at the ends of linear chromosomes. In vertebrates, a six base-pair sequence TTAGGG is repeated 100 to 1000 times to form the telomere.

While similar telomere sequences are found in most other organisms, it is not exactly the same throughout all species. However, the fact that DNA sequences are more similar in closely related organisms is evidence of the common evolutionary history shared by organisms.
