These latter movements are currently thought to be catalyzed by motor proteins that connect microtubules with opposite polarity and then "walk" toward the end of the microtubules. Mitosis ends ...

Chromosomes that lack centromeres segregate randomly during mitosis and are eventually ... polymerization, and motor-directed movements). Other kinetochore proteins are part of the spindle ...

This image depicts motor protein traffic along a single microtubule highway. Much like vehicular traffic in real life, kinesin motor traffic reduces the velocity of single motors. Multi-motor ...

Storing and processing memories uses nanoscopic motor proteins called kinesin that move materials around within neurons to construct the structural code of memory. These nanoscopic workers “walk ...

Welcome to Mitosis vs. Meiosis. This half of the screen illustrates mitosis—the division of a cell's nucleus. Along with cytokinesis (the division of the rest of a cell), mitosis results in a ...

DNA wraps around these histone proteins to form nucleosomes, which help condense nearly six feet of human genomic DNA into a ...

Cells are highly controlled spaces that rely on every protein being in the right place. Many diseases, including cancers and ...

The cell undergoes a type of cell division called mitosis. In mitosis, two cells called daughter cells are produced, each identical to the parent cell. When looking at cells with a microscope ...

As chromosomes prepare to separate, the chromatin compacts. Chromosome compaction during mitosis requires the action of condensin proteins and post-translational modifications of histone proteins. In ...

It can be seen in the stages shown above that mitosis maintains the chromosome number or complement of a cell. Mitosis therefore maintains the chromosome complement and ensures that each daughter ...

to strengthen the DNA to allow mitosis and meiosis and prevent DNA damage, and to control gene expression and DNA replication. The primary protein components of chromatin are histones that compact ...

This solution is called meiosis. Mitosis describes the process by which the nucleus of a cell divides to create two new nuclei, each containing an identical copy of DNA. (Cytokinesis describes the ...
