Answer :

Microtubules can grow by addition of tubulin dimers to both plus and minus ends (A), and they can shorten by removal of dimers from both plus and minus ends (A). So, the correct option is A. both plus and minus ends; both plus and minus ends. Correct option is A

Eukaryotic cells' cytoskeleton is made up of tubulin polymers called microtubules, which give eukaryotic cells their shape and structure. Microtubules can measure up to 50 micrometers in length, 23 to 27 nm in width, and 11 to 15 nm in inner diameter. The correct option is therefore A.
