Question

what is the image above: centriole centromere chromotid chromosome

Explanation:

The image shows a structure that is characteristic of a chromosome. A chromosome is a thread - like structure composed of DNA and proteins. It is visible during cell division. A centriole is a small organelle involved in cell division (not the structure in the image). A centromere is a part of the chromosome (the constricted region in the image, but not the whole structure). The term "chromotid" is likely a misspelling (should be chromatid, which is one half of a replicated chromosome).

Answer:

Chromosome
