👉 A microtome, also known as a microtubule, is a specialized cell organelle in the eukaryotic cell nucleus that serves as the site for the replication of DNA. It was discovered by Maurice Senden and Richard Trivers in 1953. Microtomes are responsible for the assembly and maintenance of the nuclear envelope, which protects the nucleus from damage during various cellular processes such as mitosis or cytokinesis. They also participate in the transport of genetic
