In this diagram of a duplicated chromosome, (2) identifies the centromere—the region that joins the two sister chromatids, or each half of the chromosome. In prophase of mitosis, specialized regions on centromeres called kinetochores attach chromosomes to spindle fibers. The centromere links a pair of sister chromatids together during cell ...
Centromere/kinetochore protein zw10 homolog is a protein that in humans is encoded by the ZW10 gene. [ 5 ] [ 6 ] This gene encodes a protein that is one of many involved in mechanisms to ensure proper chromosome segregation during cell division .
3' untranslated region (3'-UTR). Also three-prime untranslated region, 3' non-translated region (3'-NTR), and trailer sequence.. 3'-end. Also three-prime end.. One of two ends of a single linear strand of DNA or RNA, specifically the end at which the chain of nucleotides terminates at the third carbon atom in the furanose ring of deoxyribose or ribose (i.e. the terminus at which the 3' carbon ...
A cell during anaphase. Microtubules are visible in green. Stages of late M phase in a vertebrate cell. Anaphase (from Ancient Greek ἀνα-() 'back, backward' and φάσις (phásis) 'appearance') is the stage of mitosis after the process of metaphase, when replicated chromosomes are split and the newly-copied chromosomes (daughter chromatids) are moved to opposite poles of the cell.
The evolutionary history of the centrosome and the centriole has been traced for some of the signature genes — e.g., the centrins. [2] Centrins participate in calcium signaling and are required for centriole duplication. [28] There exist two main subfamilies of centrins, both of which are present in the early-branching eukaryote Giardia ...
Nina Andersson, from Sweden, and Derek Barclay, from Scotland, both embarked on European railway adventures in the summer of 1990. The two strangers kept crossing paths and their connection became ...
an inner kinetochore, which is tightly associated with the centromere DNA and assembled in a specialized form of chromatin that persists throughout the cell cycle; an outer kinetochore, which interacts with microtubules ; the outer kinetochore is a very dynamic structure with many identical components, which are assembled and functional only ...
Greenland is important for the United States' national security, U.S. Congressman Mike Waltz said on Wednesday, following comments by U.S. President-elect Donald Trump suggesting the U.S. should ...
